Please list or describe the changes introduced by this PR.
## Additional Info
Similar to PR #3836
## Proposed Changes
- only use LH types to avoid build issues
- use warp instead of axum for the server to avoid importing the dep
## Additional Info
- wondering if we can move the `execution_layer/test_utils` to its own crate and import it as a dev dependency
- this would be made easier by separating out our engine API types into their own crate so we can use them in the test crate
- or maybe we can look into using reth types for the engine api if they are in their own crate

Attempting to improve our CI speeds as its recently been a pain point.
Major changes:
- Use a github action to pull stable/nightly rust rather than building it each run
- Shift test suite to `nexttest` https://github.com/nextest-rs/nextest for CI
UPDATE:
So I've iterated on some changes, and although I think its still not optimal I think this is a good base to start from. Some extra things in this PR:
- Shifted where we pull rust from. We're now using this thing: https://github.com/moonrepo/setup-rust . It's got some interesting cache's built in, but was not seeing the gains that Jimmy managed to get. In either case tho, it can pull rust, cargofmt, clippy, cargo nexttest all in < 5s. So I think it's worthwhile.
- I've grouped a few of the check-like tests into a single test called `code-test`. Although we were using github runners in parallel which may be faster, it just seems wasteful. There were like 4-5 tests, where we would pull lighthouse, compile it, then run an action, like clippy, cargo-audit or fmt. I've grouped these into a single action, so we only compile lighthouse once, then in each step we run the checks. This avoids compiling lighthouse like 5 times.
- Ive made doppelganger tests run on our local machines to avoid pulling foundry, building and making lcli which are all now baked into the images.
- We have sccache and do not incremental compile lighthouse
Misc bonus things:
- Cargo update
- Fix web3 signer openssl keys which is required after a cargo update
- Use mock_instant in an LRU cache test to avoid non-deterministic test
- Remove race condition in building web3signer tests
There's still some things we could improve on. Such as downloading the EF tests every run and the web3-signer binary, but I've left these to be out of scope of this PR. I think the above are meaningful improvements.

## Issue Addressed
Synchronize dependencies and edition on the workspace `Cargo.toml`
## Proposed Changes
with https://github.com/rust-lang/cargo/issues/8415 merged it's now possible to synchronize details on the workspace `Cargo.toml` like the metadata and dependencies.
By only having dependencies that are shared between multiple crates aligned on the workspace `Cargo.toml` it's easier to not miss duplicate versions of the same dependency and therefore ease on the compile times.
## Additional Info
this PR also removes the no longer required direct dependency of the `serde_derive` crate.
should be reviewed after https://github.com/sigp/lighthouse/pull/4639 get's merged.

## Issue Addressed
#4635
## Proposed Changes
Wrap the `SignedVoluntaryExit` object in a `GenericResponse` container, adding an additional `data` layer, to ensure compliance with the key manager API specification.
The new response would look like this:
```json
{"data":{"message":{"epoch":"196868","validator_index":"505597"},"signature":"0xhexsig"}}
```
This is a backward incompatible change and will affect Siren as well.

## Proposed Changes
add SSZ support to the following block production endpoints:
GET /eth/v2/validator/blocks/{slot}
GET /eth/v1/validator/blinded_blocks/{slot}
## Additional Info
i updated a few existing tests to use ssz instead of writing completely new tests
## Issue Addressed

## Issue Addressed
Closes#4473 (take 3)
## Proposed Changes
- Send a 202 status code by default for duplicate blocks, instead of 400. This conveys to the caller that the block was published, but makes no guarantees about its validity. Block relays can count this as a success or a failure as they wish.
- For users wanting finer-grained control over which status is returned for duplicates, a flag `--http-duplicate-block-status` can be used to adjust the behaviour. A 400 status can be supplied to restore the old (spec-compliant) behaviour, or a 200 status can be used to silence VCs that warn loudly for non-200 codes (e.g. Lighthouse prior to v4.4.0).
- Update the Lighthouse VC to gracefully handle success codes other than 200. The info message isn't the nicest thing to read, but it covers all bases and isn't a nasty `ERRO`/`CRIT` that will wake anyone up.
## Additional Info
I'm planning to raise a PR to `beacon-APIs` to specify that clients may return 202 for duplicate blocks. Really it would be nice to use some 2xx code that _isn't_ the same as the code for "published but invalid". I think unfortunately there aren't any suitable codes, and maybe the best fit is `409 CONFLICT`. Given that we need to fix this promptly for our release, I think using the 202 code temporarily with configuration strikes a nice compromise.

It seems `post_validator_duties_sync` is the only api which doesn't have its own metric in `duties_service`, this PR adds `metrics::VALIDATOR_DUTIES_SYNC_HTTP_POST` for completeness.
## Issue Addressed
Addresses #2557
## Proposed Changes
Adds the `lighthouse validator-manager` command, which provides:
- `lighthouse validator-manager create`
- Creates a `validators.json` file and a `deposits.json` (same format as https://github.com/ethereum/staking-deposit-cli)
- `lighthouse validator-manager import`
- Imports validators from a `validators.json` file to the VC via the HTTP API.
- `lighthouse validator-manager move`
- Moves validators from one VC to the other, utilizing only the VC API.
## Additional Info
In 98bcb947c I've reduced some VC `ERRO` and `CRIT` warnings to `WARN` or `DEBG` for the case where a pubkey is missing from the validator store. These were being triggered when we removed a validator but still had it in caches. It seems to me that `UnknownPubkey` will only happen in the case where we've removed a validator, so downgrading the logs is prudent. All the logs are `DEBG` apart from attestations and blocks which are `WARN`. I thought having *some* logging about this condition might help us down the track.
In 856cd7e37d I've made the VC delete the corresponding password file when it's deleting a keystore. This seemed like nice hygiene. Notably, it'll only delete that password file after it scans the validator definitions and finds that no other validator is also using that password file.
## Issue Addressed
NA
## Proposed Changes
We've been seeing a lot of [CI failures](https://github.com/sigp/lighthouse/actions/runs/5781296217/job/15666209142) with errors like this:
```
---- extra_interchange_tests::export_same_key_twice stdout ----
thread 'extra_interchange_tests::export_same_key_twice' panicked at 'called `Result::unwrap()` on an `Err` value: SQLError("Unable to open database: Error(None)")', validator_client/slashing_protection/src/extra_interchange_tests.rs:48:67
```
I'm assuming they're timeouts. I noticed that tests have a 0.1s timeout. Perhaps this just doesn't cut it when our new runners are overloaded.
## Additional Info

## Issue Addressed
#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
## Issue Addressed
NA
## 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.
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`.
## Issue Addressed
Closes https://github.com/sigp/lighthouse/issues/4291, part of #3613.
## Proposed Changes
- Implement the `el_offline` field on `/eth/v1/node/syncing`. We set `el_offline=true` if:
- The EL's internal status is `Offline` or `AuthFailed`, _or_
- The most recent call to `newPayload` resulted in an error (more on this in a moment).
- Use the `el_offline` field in the VC to mark nodes with offline ELs as _unsynced_. These nodes will still be used, but only after synced nodes.
- Overhaul the usage of `RequireSynced` so that `::No` is used almost everywhere. The `--allow-unsynced` flag was broken and had the opposite effect to intended, so it has been deprecated.
- Add tests for the EL being offline on the upcheck call, and being offline due to the newPayload check.
## Why track `newPayload` errors?
Tracking the EL's online/offline status is too coarse-grained to be useful in practice, because:
- If the EL is timing out to some calls, it's unlikely to timeout on the `upcheck` call, which is _just_ `eth_syncing`. Every failed call is followed by an upcheck [here](693886b941/beacon_node/execution_layer/src/engines.rs (L372-L380)), which would have the effect of masking the failure and keeping the status _online_.
- The `newPayload` call is the most likely to time out. It's the call in which ELs tend to do most of their work (often 1-2 seconds), with `forkchoiceUpdated` usually returning much faster (<50ms).
- If `newPayload` is failing consistently (e.g. timing out) then this is a good indication that either the node's EL is in trouble, or the network as a whole is. In the first case validator clients _should_ prefer other BNs if they have one available. In the second case, all of their BNs will likely report `el_offline` and they'll just have to proceed with trying to use them.
## Additional Changes
- Add utility method `ForkName::latest` which is quite convenient for test writing, but probably other things too.
- Delete some stale comments from when we used to support multiple execution nodes.
It is a well-known fact that IP addresses for beacon nodes used by specific validators can be de-anonymized. There is an assumed risk that a malicious user may attempt to DOS validators when producing blocks to prevent chain growth/liveness.
Although there are a number of ideas put forward to address this, there a few simple approaches we can take to mitigate this risk.
Currently, a Lighthouse user is able to set a number of beacon-nodes that their validator client can connect to. If one beacon node is taken offline, it can fallback to another. Different beacon nodes can use VPNs or rotate IPs in order to mask their IPs.
This PR provides an additional setup option which further mitigates attacks of this kind.
This PR introduces a CLI flag --proposer-only to the beacon node. Setting this flag will configure the beacon node to run with minimal peers and crucially will not subscribe to subnets or sync committees. Therefore nodes of this kind should not be identified as nodes connected to validators of any kind.
It also introduces a CLI flag --proposer-nodes to the validator client. Users can then provide a number of beacon nodes (which may or may not run the --proposer-only flag) that the Validator client will use for block production and propagation only. If these nodes fail, the validator client will fallback to the default list of beacon nodes.
Users are then able to set up a number of beacon nodes dedicated to block proposals (which are unlikely to be identified as validator nodes) and point their validator clients to produce blocks on these nodes and attest on other beacon nodes. An attack attempting to prevent liveness on the eth2 network would then need to preemptively find and attack the proposer nodes which is significantly more difficult than the default setup.
This is a follow on from: #3328

## Title
Optimise `update_validators` by decrypting key cache only when necessary
## Issue Addressed
Resolves [#3968: Slow performance of validator client PATCH API with hundreds of keys](https://github.com/sigp/lighthouse/issues/3968)
## Proposed Changes
1. Add a check to determine if there is at least one local definition before decrypting the key cache.
2. Assign an empty `KeyCache` when all definitions are of the `Web3Signer` type.
3. Perform cache-related operations (e.g., saving the modified key cache) only if there are local definitions.
## Additional Info
This PR addresses the excessive CPU usage and slow performance experienced when using the `PATCH lighthouse/validators/{pubkey}` request with a large number of keys. The issue was caused by the key cache using cryptography to decipher and cipher the cache entities every time the request was made. This operation called `scrypt`, which was very slow and required a lot of memory when there were many concurrent requests.
These changes have no impact on the overall functionality but can lead to significant performance improvements when working with remote signers. Importantly, the key cache is never used when there are only `Web3Signer` definitions, avoiding the expensive operation of decrypting the key cache in such cases.
