* `engine_api_response_time` provides a histogram for the Engine API
response times for each unique pair ot URL and request type.
* All engine API requests are now tracked
Other changes:
The client will no longer exit on start-up if it fails to connect to
a properly configured EL node.
When using `--history=prune`, `dag.tail.slot` may advance beyond the
configured light client data retention period. Update the LC logic so
that the `dag.tail.slot` is no longer considered for LC pruning.
It is still considered to check whether new data can be produced.
* Update sync to use post-decoupling RPCs
blob_sidecars_by_range returns a flat list of sidecars, which must
then be grouped per-slot.
* Add test for groupBlobs
* createBlobs: convert proc to func
* Support for driving multiple EL nodes from a single Nimbus BN
Full list of changes:
* Eth1Monitor has been renamed to ELManager to match its current
responsibilities better.
* The ELManager is no longer optional in the code (it won't have
a nil value under any circumstances).
* The support for subscribing for headers was removed as it only
worked with WebSockets and contributed significant complexity
while bringing only a very minor advantage.
* The `--web3-url` parameter has been deprecated in favor of a
new `--el` parameter. The new parameter has a reasonable default
value and supports specifying a different JWT for each connection.
Each connection can also be configured with a different set of
responsibilities (e.g. download deposits, validate blocks and/or
produce blocks). On the command-line, these properties can be
configured through URL properties stored in the #anchor part of
the URL. In TOML files, they come with a very natural syntax
(althrough the URL scheme is also supported).
* The previously scattered EL-related state and logic is now moved
to `eth1_monitor.nim` (this module will be renamed to `el_manager.nim`
in a follow-up commit). State is assigned properly either to the
`ELManager` or the to individual `ELConnection` objects where
appropriate.
The ELManager executes all Engine API requests against all attached
EL nodes, in parallel. It compares their results and if there is a
disagreement regarding the validity of a certain payload, this is
detected and the beacon node is protected from publishing a block
with a potential execution layer consensus bug in it.
The BN provides metrics per EL node for the number of successful or
failed requests for each type Engine API requests. If an EL node
goes offline and connectivity is resoted later, we report the
problem and the remedy in edge-triggered fashion.
* More progress towards implementing Deneb block production in the VC
and comparing the value of blocks produced by the EL and the builder
API.
* Adds a Makefile target for the zhejiang testnet
* Fix issue when VC unable to detect errors properly and act accordingly.
Switch all API functions used by VC to RestPlainResponse, this allows us to print errors returned by BN servers.
* Fix issue when prepareBeaconCommitteeSubnet() do not perform actions when BN is optimistically synced only.
* Fix Defect issue.
* Fix submit/publish returning `false` when operation was successful.
* Address review comments.
* Fix some client calls unable to receive `execution_optimistic` field, mark BN as OptSynced when such request has been made.
* Adjust warning levels.

Sepolia in particular goes through two hard forks during era 1, meaning
the phase0 fork is no longer part of the state, even though blocks that
belong to it still are phase0.
* log validator that triggers doppelganger
* move activity detection closer to where it's performed, record
aggregation as activity (since it's part of the liveness endpoint)
* vc: check for doppelgangers in epoch 0 also (so that activity in epoch
1 can happen)
* avoid some looping when processing activities
* Remove use of beacon_block_and_blobs_sidecar topic
This topic goes away with decoupled blocks and blobs.
* remove use of getBeaconBlockAndBlobsSidecarTopic from test
* update nimbus_light_client.nim
This commit removes ForkySignedBeaconBlockMaybeBlobs and all
references. I tried to pull that thread only as little as was needed
to get rid of it. Left a placeholder BlobSidecar array (in lieu of
Opt[BlobsSidecar]) in a few places; this will be used as we rebuild
the decoupled implementation.
First step in debugging issue most probably re-introduced by:
https://github.com/status-im/nimbus-eth2/pull/4551
Which causes the finalization tests script to kill other processes
unrelated to the given CI job.
