#4118
## Proposed Changes
This PR introduces a "progressive balances" cache on the `BeaconState`, which keeps track of the accumulated target attestation balance for the current & previous epochs. The cached values are utilised by fork choice to calculate unrealized justification and finalization (instead of converting epoch participation arrays to balances for each block we receive).
This optimization will be rolled out gradually to allow for more testing. A new `--progressive-balances disabled|checked|strict|fast` flag is introduced to support this:
- `checked`: enabled with checks against participation cache, and falls back to the existing epoch processing calculation if there is a total target attester balance mismatch. There is no performance gain from this as the participation cache still needs to be computed. **This is the default mode for now.**
- `strict`: enabled with checks against participation cache, returns error if there is a mismatch. **Used for testing only**.
- `fast`: enabled with no comparative checks and without computing the participation cache. This mode gives us the performance gains from the optimization. This is still experimental and not currently recommended for production usage, but will become the default mode in a future release.
- `disabled`: disable the usage of progressive cache, and use the existing method for FFG progression calculation. This mode may be useful if we find a bug and want to stop the frequent error logs.
### Tasks
- [x] Initial cache implementation in `BeaconState`
- [x] Perform checks in fork choice to compare the progressive balances cache against results from `ParticipationCache`
- [x] Add CLI flag, and disable the optimization by default
- [x] Testing on Goerli & Benchmarking
- [x] Move caching logic from state processing to the `ProgressiveBalancesCache` (see [this comment](https://github.com/sigp/lighthouse/pull/4362#discussion_r1230877001))
- [x] Add attesting balance metrics

## Proposed Changes
debounce spammy `Unable to send message to the beacon processor` log messages
## Additional Info
We could potentially debounce other logs that have the potential to be "spammy".
After some feedback we decided to additionally add the following change:
create a newtype wrapper around `mpsc::Sender<BeaconWorkEvent<T>>`. When there is an error on the try_send method on the wrapper, we increase a counter metric with one label per work type.

## Proposed Changes
Implements the `PrettyReqwestError` to wrap a `reqwest::Error` and give nicer `Debug` formatting. It also wraps the `Url` component in a `SensitiveUrl` to avoid leaking sensitive info in logs.
### Before
```
Reqwest(reqwest::Error { kind: Request, url: Url { scheme: "http", cannot_be_a_base: false, username: "", password: None, host: Some(Domain("localhost")), port: Some(9999), path: "/eth/v1/node/version", query: None, fragment: None }, source: hyper::Error(Connect, ConnectError("tcp connect error", Os { code: 61, kind: ConnectionRefused, message: "Connection refused" })) })
```
### After
```
HttpClient(url: http://localhost:9999/, kind: request, detail: error trying to connect: tcp connect error: Connection refused (os error 61))
```
## Additional Info
I've also renamed the `Reqwest` error enum variants to `HttpClient`, to give people a better chance at knowing what's going on. Reqwest is pretty odd and looks like a typo.
I've implemented it in the `eth2` and `execution_layer` crates. This should affect most logs in the VC and EE-related ones in the BN.
I think the last crate that could benefit from the is the `beacon_node/eth1` crate. I haven't updated it in this PR since its error type is not so amenable to it (everything goes into a `String`). I don't have a whole lot of time to jig around with that at the moment and I feel that this PR as it stands is a significant enough improvement to merge on its own. Leaving it as-is is fine for the time being and we can always come back for it later (or implement in-protocol deposits!).

#4386
## Proposed Changes
The original proposal described in the issue adds a new endpoint to support updating validator graffiti, but I realized we already have an endpoint that we use for updating various validator fields in memory and in the validator definitions file, so I think that would be the best place to add this to.
### API endpoint
`PATCH lighthouse/validators/{validator_pubkey}`
This endpoint updates the graffiti in both the [ validator definition file](https://lighthouse-book.sigmaprime.io/graffiti.html#2-setting-the-graffiti-in-the-validator_definitionsyml) and the in memory `InitializedValidators`. In the next block proposal, the new graffiti will be used.
Note that the [`--graffiti-file`](https://lighthouse-book.sigmaprime.io/graffiti.html#1-using-the---graffiti-file-flag-on-the-validator-client) flag has a priority over the validator definitions file, so if the caller attempts to update the graffiti while the `--graffiti-file` flag is present, the endpoint will return an error (Bad request 400).
## Tasks
- [x] Add graffiti update support to `PATCH lighthouse/validators/{validator_pubkey}`
- [x] Return error if user tries to update graffiti while the `--graffiti-flag` is set
- [x] Update Lighthouse book
## Issue Addressed
NA
## Proposed Changes
Adds the `--validator-registration-batch-size` flag to the VC to allow runtime configuration of the number of validators POSTed to the [`validator/register_validator`](https://ethereum.github.io/beacon-APIs/?urls.primaryName=dev#/Validator/registerValidator) endpoint.
There are builders (Agnostic and Eden) that are timing out with `regsiterValidator` requests with ~400 validators, even with a 9 second timeout. Exposing the batch size will help tune batch sizes to (hopefully) avoid this.
This PR should not change the behavior of Lighthouse when the new flag is not provided (i.e., the same default value is used).
## Additional Info
NA
## Proposed Changes
Remove `max-skip-slots` checks when processing blocks.
This was legacy code which was previously used in the Medalla testnet to sync to the correct fork.
With the addition of checkpoint sync which allows us to sync to any arbitrary fork, this is no longer a necessary feature, so it has been removed for simplicity.
## Additional Notes
The CLI flag and checks for attestation processing have been retained as it still may have uses in DoS protection.
Currently, the ENR of the node may not be correctly updated when specifying ipv6 fields through the CLI if an ENR exists on disk.
This remedies a bug where we were not checking for ipv6 fields when comparing whether to use an on-disk ENR or updating based on CLI configuration parameters.
This is only a minor correction to the table not properly showing up in Lighthouse book. The changes solves the formatting issue. Another change is on the link to do port-forwarding.
## Issue Addressed
Closes#4332
## Proposed Changes
Remove the `CountUnrealized` type, defaulting unrealized justification to _on_. This fixes the #4332 issue by ensuring that importing the same block to fork choice always results in the same outcome.
Finalized sync speed may be slightly impacted by this change, but that is deemed an acceptable trade-off until the optimisation from #4118 is implemented.
TODO:
- [x] Also check that the block isn't a duplicate before importing
Checkpointz now supports deposit snapshot but [they only support returning them in JSON](https://github.com/ethpandaops/checkpointz/issues/74) so I've modified lighthouse to request them in JSON by default.
There's also `get_opt` & `get_opt_with_timeout` methods which seem to expect responses in JSON but were not adding `Accept: application/json` to the request headers so I fixed that as well.
Also the beacon API puts quantities in quotes so I fixed that in the snapshot JSON serialization

## Proposed Changes
Downgrade a `CRIT` to an `ERRO` when there's an `Irrecoverable` error whilst publishing a blinded block.
It's quite common for builders successfully broadcast a block to the network whilst failing to respond to the BN when it publishes a signed, blinded block. The VC is currently raising a `CRIT` when this happens and I think that's excessive.
These changes have the same intent as #4073. In that PR I only managed to remove the `CRIT`s in the BN but missed this one in the VC.
I've also tidied the log messages to:
- Give them all the same title (*"Error whilst producing block"*) to help with grepping.
- Include the `block_slot` so it's easy to look up the slot in an explorer and see if it was actually skipped.
## Additional Info
This PR should not change any logic beyond logging.
## Issue Addressed
Closes#4354Closes#3987
Replaces #4305, #4283
## Proposed Changes
This switches the default slasher backend _back_ to LMDB.
If an MDBX database exists and the MDBX backend is enabled then MDBX will continue to be used. Our release binaries and Docker images will continue to include MDBX for as long as it is practical, so users of these should not notice any difference.
The main benefit is to users compiling from source and devs running tests. These users no longer have to struggle to compile MDBX and deal with the compatibility issues that arises. Similarly, devs don't need to worry about toggling feature flags in tests or risk forgetting to run the slasher tests due to backend issues.

## Proposed Changes
This change will log the value of the relay block and the local block when the relay block is more profitable.
## Additional Info
This change will help validators understand the block selection (as it looks like the execution reward sometimes is higher that the MEV-reward).
The rationale for this change is to aid operators to better understand why a relay-block was chosen over a local block.
Looking at produced blocks (at beaconcha.in for example) it sometimes looks like the builder is making a profit just from the execution reward vs the MEV-reward, and creates the nagging question: "Could i have built this block and made that extra profit?"... The answer is probably "No, not without the extra transactions included by the relay", but by logging the value of the local block-candidate, this will no longer be an issue..

## Issue Addressed
On deneb devnetv5, lighthouse keeps rate limiting peers which makes it harder to bootstrap new nodes as there are very few peers in the network. This PR adds an option to disable the inbound rate limiter for testnets.

## Proposed Changes
This is a light refactor of the execution layer's block hash calculation logic making it easier to use externally. e.g. in `eleel` (https://github.com/sigp/eleel/pull/18).
A static method is preferable to a method because the calculation doesn't actually need any data from `self`, and callers may want to compute block hashes without constructing an `ExecutionLayer` (`eleel` only constructs a simpler `Engine` struct).

This PR address the following spec change: https://github.com/ethereum/consensus-specs/pull/3312
Instead of subscribing to a long-lived subnet for every attached validator to a beacon node, all beacon nodes will subscribe to `SUBNETS_PER_NODE` long-lived subnets. This is currently set to 2 for mainnet.
This PR does not include any scoring or advanced discovery mechanisms. A future PR will improve discovery and we can implement scoring after the next hard fork when we expect all client teams and all implementations to respect this spec change.
This will be a significant change in the subnet network structure for consensus clients and we will likely have to monitor and tweak our peer management logic.

Geth's latest release breaks our CI with the following message
```
Fatal: Failed to register the Ethereum service: ethash is only supported as a historical component of already merged networks
Shutting down

Latest geth version has removed support for PoW networks. Hence, we need to add an extra `terminalTotalDifficultyPassed ` parameter in the genesis config to start from a merged network.
## Issue Addressed
Add a new `--output values` option to `db inspect` for dumping raw database values to SSZ files.
This could be useful for inspecting the database when we're unable to start the beacon node.
Example usage:

# Output the `ForkChoice` column to an SSZ file
lighthouse db inspect --column frk --output values
```
By default, it stores the output files in the current directory, and can be overriden with `--ouput-dir`.

This PR adds the ability to read the Lighthouse logs from the HTTP API for both the BN and the VC.
This is done in such a way to as minimize any kind of performance hit by adding this feature.
The current design creates a tokio broadcast channel and mixes is into a form of slog drain that combines with our main global logger drain, only if the http api is enabled.
The drain gets the logs, checks the log level and drops them if they are below INFO. If they are INFO or higher, it sends them via a broadcast channel only if there are users subscribed to the HTTP API channel. If not, it drops the logs.
If there are more than one subscriber, the channel clones the log records and converts them to json in their independent HTTP API tasks.

## Issue Addressed
https://github.com/sigp/lighthouse/pull/4309#issuecomment-1556052261
## Proposed Changes
Log the `Connected to beacon node` message only if the node was previously offline. This avoids a regression in logging after #4295, whereby the `Connected to beacon node` message would be logged every slot.
The new reduced logging is _slightly different_ from what we had prior to my changes in #4295. The main difference is that we used to log the `Connected` message whenever a node was online and subject to a health check (for being unhealthy in some other way). I think the new behaviour is reasonable, as the `Connected` message isn't particularly helpful if the BN is unhealthy, and the specific reason for unhealthiness will be logged by the warnings for `is_compatible`/`is_synced`.
