01556f6f01 Optimise payload attributes calculation and add SSE (#4027)
## Issue Addressed

Closes #3896
Closes #3998
Closes #3700

## Proposed Changes

- Optimise the calculation of withdrawals for payload attributes by avoiding state clones, avoiding unnecessary state advances and reading from the snapshot cache if possible.
- Use the execution layer's payload attributes cache to avoid re-calculating payload attributes. I actually implemented a new LRU cache just for withdrawals but it had the exact same key and most of the same data as the existing payload attributes cache, so I deleted it.
- Add a new SSE event that fires when payloadAttributes are calculated. This is useful for block builders, a la https://github.com/ethereum/beacon-APIs/issues/244.
- Add a new CLI flag `--always-prepare-payload` which forces payload attributes to be sent with every fcU regardless of connected proposers. This is intended for use by builders/relays.

For maximum effect, the flags I've been using to run Lighthouse in "payload builder mode" are:

```
--always-prepare-payload \
--prepare-payload-lookahead 12000 \
--suggested-fee-recipient 0x0000000000000000000000000000000000000000
```

The fee recipient is required so Lighthouse has something to pack in the payload attributes (it can be ignored by the builder). The lookahead causes fcU to be sent at the start of every slot rather than at 8s. As usual, fcU will also be sent after each change of head block. I think this combination is sufficient for builders to build on all viable heads. Often there will be two fcU (and two payload attributes) sent for the same slot: one sent at the start of the slot with the head from `n - 1` as the parent, and one sent after the block arrives with `n` as the parent.

Example usage of the new event stream:

```bash
curl -N "http://localhost:5052/eth/v1/events?topics=payload_attributes"
```

## Additional Info

- [x] Tests added by updating the proposer re-org tests. This has the benefit of testing the proposer re-org code paths with withdrawals too, confirming that the new changes don't interact poorly.
- [ ] Benchmarking with `blockdreamer` on devnet-7 showed promising results but I'm yet to do a comparison to `unstable`.

cac3a66be4 Permit a null LVH from an INVALID response to newPayload (#4037)
## Issue Addressed

NA

## Proposed Changes

As discovered in #4034, Lighthouse is not accepting `latest_valid_hash == None` in an `INVALID` response to `newPayload`. The `null`/`None` response *was* illegal at one point, however it was added in https://github.com/ethereum/execution-apis/pull/254.

This PR brings Lighthouse in line with the standard and should fix the root cause of what #4034 patched around.

047c7544e3 Clean capella (#4019)
## Issue Addressed

Cleans up all the remnants of 4844 in capella. This makes sure when 4844 is reviewed there is nothing we are missing because it got included here 

## Proposed Changes

drop a bomb on every 4844 thing 

## Additional Info

Merge process I did (locally) is as follows:
- squash merge to produce one commit
- in new branch off unstable with the squashed commit create a `git revert HEAD` commit
- merge that new branch onto 4844 with `--strategy ours`
- compare local 4844 to remote 4844 and make sure the diff is empty
- enjoy

47b22d5256 Allow compilation with no slasher backend (#3888)
## Proposed Changes

Allowing compiling without MDBX by running:

```bash
CARGO_INSTALL_EXTRA_FLAGS="--no-default-features" make
```

The reasons to do this are several:

- Save compilation time if the slasher won't be used
- Work around compilation errors in slasher backend dependencies (our pinned version of MDBX is currently not compiling on FreeBSD with certain compiler versions).

## Additional Info

When I opened this PR we were using resolver v1 which [doesn't disable default features in dependencies](https://doc.rust-lang.org/cargo/reference/features.html#resolver-version-2-command-line-flags), and `mdbx` is default for the `slasher` crate. Even after the resolver got changed to v2 in #3697 compiling with `--no-default-features` _still_ wasn't turning off the slasher crate's default features, so I added `default-features = false` in all the places we depend on it.

3642efe76a Cache validator balances and allow them to be served over the HTTP API (#3863)
## Issue Addressed

#3804

## Proposed Changes

- Add `total_balance` to the validator monitor and adjust the number of historical epochs which are cached. 
- Allow certain values in the cache to be served out via the HTTP API without requiring a state read.

## Usage
```
curl -X POST "http://localhost:5052/lighthouse/ui/validator_info" -d '{"indices": [0]}' -H "Content-Type: application/json" | jq
```

```
{
  "data": {
    "validators": {
      "0": {
        "info": [
          {
            "epoch": 172981,
            "total_balance": 36566388519
          },
         ...
          {
            "epoch": 172990,
            "total_balance": 36566496513
          }
        ]
      },
      "1": {
        "info": [
          {
            "epoch": 172981,
            "total_balance": 36355797968
          },
          ...
          {
            "epoch": 172990,
            "total_balance": 36355905962
          }
        ]
      }
    }
  }
}
```

## Additional Info

This requires no historical states to operate which mean it will still function on the freshly checkpoint synced node, however because of this, the values will populate each epoch (up to a maximum of 10 entries).

Another benefit of this method, is that we can easily cache any other values which would normally require a state read and serve them via the same endpoint. However, we would need be cautious about not overly increasing block processing time by caching values from complex computations.

This also caches some of the validator metrics directly, rather than pulling them from the Prometheus metrics when the API is called. This means when the validator count exceeds the individual monitor threshold, the cached values will still be available.

Suggestions for Capella beacon_chain (#3999)
* Remove CapellaReadiness::NotSynced

Some EEs have a habit of flipping between synced/not-synced, which causes some
spurious "Not read for the merge" messages back before the merge. For the
merge, if the EE wasn't synced the CE simple wouldn't go through the transition
(due to optimistic sync stuff). However, we don't have that hard requirement
for Capella; the CE will go through the fork and just wait for the EE to catch
up. I think that removing `NotSynced` here will avoid false-positives on the
"Not ready logs..". We'll be creating other WARN/ERRO logs if the EE isn't
synced, anyway.

* Change some Capella readiness logging

There's two changes here:

1. Shorten the log messages, for readability.
2. Change the hints.

Connecting a Capella-ready LH to a non-Capella-ready EE gives this log:

```
WARN Not ready for Capella                   info: The execution endpoint does not appear to support the required engine api methods for Capella: Required Methods Unsupported: engine_getPayloadV2 engine_forkchoiceUpdatedV2 engine_newPayloadV2, service: slot_notifier
```

This variant of error doesn't get a "try updating" style hint, when it's the
one that needs it. This is because we detect the method-not-found reponse from
the EE and return default capabilities, rather than indicating that the request
fails. I think it's fair to say that an EE upgrade is required whenever it
doesn't provide the required methods.

I changed the `ExchangeCapabilitiesFailed` message since that can only happen
when the EE fails to respond with anything other than success or not-found.

2f456ff9eb Fix regression in DB write atomicity (#3931)
## Issue Addressed

Fix a bug introduced by #3696. The bug is not expected to occur frequently, so releasing this PR is non-urgent.

## Proposed Changes

* Add a variant to `StoreOp` that allows a raw KV operation to be passed around.
* Return to using `self.store.do_atomically` rather than `self.store.hot_db.do_atomically`. This streamlines the write back into a single call and makes our auto-revert work again.
* Prevent `import_block_update_shuffling_cache` from failing block import. This is an outstanding bug from before v3.4.0 which may have contributed to some random unexplained database corruption.

## Additional Info

In #3696 I split the database write into two calls, one to convert the `StoreOp`s to `KeyValueStoreOp`s and one to write them. This had the unfortunate side-effect of damaging our atomicity guarantees in case of a write error. If the first call failed, we would be left with the block in fork choice but not on-disk (or the snapshot cache), which would prevent us from processing any descendant blocks. On `unstable` the first call is very unlikely to fail unless the disk is full, but on `tree-states` the conversion is more involved and a user reported database corruption after it failed in a way that should have been recoverable.

Additionally, as @emhane observed, #3696 also inadvertently removed the import of the new block into the block cache. Although this seems like it could have negatively impacted performance, there are several mitigating factors:

- For regular block processing we should almost always load the parent block (and state) from the snapshot cache.
- We often load blinded blocks, which bypass the block cache anyway.
- Metrics show no noticeable increase in the block cache miss rate with v3.4.0.

However, I expect the block cache _will_ be useful again in `tree-states`, so it is restored to use by this PR.

5276dd0cb0 Fix edge-case when finding the finalized descendant (#3924)
## Issue Addressed

NA

## Description

We were missing an edge case when checking to see if a block is a descendant of the finalized checkpoint. This edge case is described for one of the tests in this PR:

a119edc739/consensus/proto_array/src/proto_array_fork_choice.rs (L1018-L1047)

This bug presented itself in the following mainnet log:

```
Jan 26 15:12:42.841 ERRO Unable to validate attestation error: MissingBeaconState(0x7c30cb80ec3d4ec624133abfa70e4c6cfecfca456bfbbbff3393e14e5b20bf25), peer_id: 16Uiu2HAm8RPRciXJYtYc5c3qtCRdrZwkHn2BXN3XP1nSi1gxHYit, type: "unaggregated", slot: Slot(5660161), beacon_block_root: 0x4a45e59da7cb9487f4836c83bdd1b741b4f31c67010c7ae343fa6771b3330489
```

Here the BN is rejecting an attestation because of a "missing beacon state". Whilst it was correct to reject the attestation, it should have rejected it because it attests to a block that conflicts with finality rather than claiming that the database is inconsistent.

The block that this attestation points to (`0x4a45`) is block `C` in the above diagram. It is a non-canonical block in the first slot of an epoch that conflicts with the finalized checkpoint. Due to our lazy pruning of proto array, `0x4a45` was still present in proto-array. Our missed edge-case in [`ForkChoice::is_descendant_of_finalized`](38514c07f2/consensus/fork_choice/src/fork_choice.rs (L1375-L1379)) would have indicated to us that the block is a descendant of the finalized block. Therefore, we would have accepted the attestation thinking that it attests to a descendant of the finalized *checkpoint*.

Since we didn't have the shuffling for this erroneously processed block, we attempted to read its state from the database. This failed because we prune states from the database by keeping track of the tips of the chain and iterating back until we find a finalized block. This would have deleted `C` from the database, hence the `MissingBeaconState` error.

0866b739d0 Clippy 1.67 (#3916)
## Proposed Changes

Clippy 1.67.0 put us on blast for the size of some of our errors, most of them written by me ( 👀 ). This PR shrinks the size of `BeaconChainError` by dropping some extraneous info and boxing an inner error which should only occur infrequently anyway.

For the `AttestationSlashInfo` and `BlockSlashInfo` I opted to ignore the lint as they are always used in a `Result<A, Info>` where `A` is a similar size. This means they don't bloat the size of the `Result`, so it's a bit annoying for Clippy to report this as an issue.

I also chose to ignore `clippy::uninlined-format-args` because I think the benefit-to-churn ratio is too low. E.g. sometimes we have long identifiers in `format!` args and IMO the non-inlined form is easier to read:

```rust
// I prefer this...
format!(
    "{} did {} to {}",
    REALLY_LONG_CONSTANT_NAME,
    ANOTHER_REALLY_LONG_CONSTANT_NAME,
    regular_long_identifier_name
);
  
// To this
format!("{REALLY_LONG_CONSTANT_NAME} did {ANOTHER_REALLY_LONG_CONSTANT_NAME} to {regular_long_identifier_name}");
```

I tried generating an automatic diff with `cargo clippy --fix` but it came out at:

```
250 files changed, 1209 insertions(+), 1469 deletions(-)
```

Which seems like a bad idea when we'd have to back-merge it to `capella` and `eip4844` 😱

a7351c00c0 light client optimistic update reprocessing (#3799)
## Issue Addressed
Currently there is a race between receiving blocks and receiving light client optimistic updates (in unstable), which results in processing errors. This is a continuation of PR #3693 and seeks to progress on issue #3651

## Proposed Changes

Add the parent_root to ReprocessQueueMessage::BlockImported so we can remove blocks from queue when a block arrives that has the same parent root. We use the parent root as opposed to the block_root because the LightClientOptimisticUpdate does not contain the block_root.

If light_client_optimistic_update.attested_header.canonical_root() != head_block.message().parent_root() then we queue the update. Otherwise we process immediately.
## Additional Info
michaelsproul came up with this idea.
The code was heavily based off of the attestation reprocessing.
I have not properly tested this to see if it works as intended.

830efdb5c2 Improve validator monitor experience for high validator counts (#3728)
## Issue Addressed

NA

## Proposed Changes

Myself and others (#3678) have observed  that when running with lots of validators (e.g., 1000s) the cardinality is too much for Prometheus. I've seen Prometheus instances just grind to a halt when we turn the validator monitor on for our testnet validators (we have 10,000s of Goerli validators). Additionally, the debug log volume can get very high with one log per validator, per attestation.

To address this, the `bn --validator-monitor-individual-tracking-threshold <INTEGER>` flag has been added to *disable* per-validator (i.e., non-aggregated) metrics/logging once the validator monitor exceeds the threshold of validators. The default value is `64`, which is a finger-to-the-wind value. I don't actually know the value at which Prometheus starts to become overwhelmed, but I've seen it work with ~64 validators and I've seen it *not* work with 1000s of validators. A default of `64` seems like it will result in a breaking change to users who are running millions of dollars worth of validators whilst resulting in a no-op for low-validator-count users. I'm open to changing this number, though.

Additionally, this PR starts collecting aggregated Prometheus metrics (e.g., total count of head hits across all validators), so that high-validator-count validators still have some interesting metrics. We already had logging for aggregated values, so nothing has been added there.

I've opted to make this a breaking change since it can be rather damaging to your Prometheus instance to accidentally enable the validator monitor with large numbers of validators. I've crashed a Prometheus instance myself and had a report from another user who's done the same thing.

## Additional Info

NA

## Breaking Changes Note

A new label has been added to the validator monitor Prometheus metrics: `total`. This label tracks the aggregated metrics of all validators in the validator monitor (as opposed to each validator being tracking individually using its pubkey as the label).

Additionally, a new flag has been added to the Beacon Node: `--validator-monitor-individual-tracking-threshold`. The default value is `64`, which means that when the validator monitor is tracking more than 64 validators then it will stop tracking per-validator metrics and only track the `all_validators` metric. It will also stop logging per-validator logs and only emit aggregated logs (the exception being that exit and slashing logs are always emitted).

These changes were introduced in #3728 to address issues with untenable Prometheus cardinality and log volume when using the validator monitor with high validator counts (e.g., 1000s of validators). Users with less than 65 validators will see no change in behavior (apart from the added `all_validators` metric). Users with more than 65 validators who wish to maintain the previous behavior can set something like `--validator-monitor-individual-tracking-threshold 999999`.

4bd2b777ec Verify execution block hashes during finalized sync (#3794)
## Issue Addressed

Recent discussions with other client devs about optimistic sync have revealed a conceptual issue with the optimisation implemented in #3738. In designing that feature I failed to consider that the execution node checks the `blockHash` of the execution payload before responding with `SYNCING`, and that omitting this check entirely results in a degradation of the full node's validation. A node omitting the `blockHash` checks could be tricked by a supermajority of validators into following an invalid chain, something which is ordinarily impossible.

## Proposed Changes

I've added verification of the `payload.block_hash` in Lighthouse. In case of failure we log a warning and fall back to verifying the payload with the execution client.

I've used our existing dependency on `ethers_core` for RLP support, and a new dependency on Parity's `triehash` crate for the Merkle patricia trie. Although the `triehash` crate is currently unmaintained it seems like our best option at the moment (it is also used by Reth, and requires vastly less boilerplate than Parity's generic `trie-root` library).

Block hash verification is pretty quick, about 500us per block on my machine (mainnet).

The optimistic finalized sync feature can be disabled using `--disable-optimistic-finalized-sync` which forces full verification with the EL.

## Additional Info

This PR also introduces a new dependency on our [`metastruct`](https://github.com/sigp/metastruct) library, which was perfectly suited to the RLP serialization method. There will likely be changes as `metastruct` grows, but I think this is a good way to start dogfooding it.

I took inspiration from some Parity and Reth code while writing this, and have preserved the relevant license headers on the files containing code that was copied and modified.
