move quarantine outside of chaindag (#3124) * move quarantine outside of chaindag The quarantine has been part of the ChainDAG for the longest time, but this design has a few issues: * the function in which blocks are verified and added to the dag becomes reentrant and therefore difficult to reason about - we're currently using a stateful flag to work around it * quarantined blocks bypass the processing queue leading to a processing stampede * the quarantine flow is unsuitable for orphaned attestations - these should also should be quarantined eventually Instead of processing the quarantine inside ChainDAG, this PR moves re-queueing to `block_processor` which already is responsible for dealing with follow-up work when a block is added to the dag This sets the stage for keeping attestations in the quarantine as well. Also: * make `BlockError` `{.pure.}` * avoid use of `ValidationResult` in block clearance (that's for gossip)

This function is meanwhile a simple wrapper around `nim-bearssl`'s `HmacDrbgContext.new()`, so the import doesn't really serve a use anymore. Replace `keys.newRng` with the direct call to reduce `nim-eth` imports.

Validator monitoring (#2925) Validator monitoring based on and mostly compatible with the implementation in Lighthouse - tracks additional logs and metrics for specified validators so as to stay on top on performance. The implementation works more or less the following way: * Validator pubkeys are singled out for monitoring - these can be running on the node or not * For every action that the validator takes, we record steps in the process such as messages being seen on the network or published in the API * When the dust settles at the end of an epoch, we report the information from one epoch before that, which coincides with the balances being updated - this is a tradeoff between being correct (waiting for finalization) and providing relevant information in a timely manner)

Support for driving multiple EL nodes from a single Nimbus BN (#4465) * 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

time: spring cleaning (#3262) Time in the beacon chain is expressed relative to the genesis time - this PR creates a `beacon_time` module that collects helpers and utilities for dealing the time units - the new module does not deal with actual wall time (that's remains in `beacon_clock`). Collecting the time related stuff in one place makes it easier to find, avoids some circular imports and allows more easily identifying the code actually needs wall time to operate. * move genesis-time-related functionality into `spec/beacon_time` * avoid using `chronos.Duration` for time differences - it does not support negative values (such as when something happens earlier than it should) * saturate conversions between `FAR_FUTURE_XXX`, so as to avoid overflows * fix delay reporting in validator client so it uses the expected deadline of the slot, not "closest wall slot" * simplify looping over the slots of an epoch * `compute_start_slot_at_epoch` -> `start_slot` * `compute_epoch_at_slot` -> `epoch` A follow-up PR will (likely) introduce saturating arithmetic for the time units - this is merely code moves, renames and fixing of small bugs.

Fetch by-root request directly from quarantine (#5167) When the requestmanager is busy fetching blocks, the queue might get filled with multiple entries of the same root - since there is no deduplication, requests containing the same root multiple times will be sent out. Also, because the items sit in the queue for a long time potentially, the request might be stale by the time that the manager is ready with the previous request. This PR removes the queue and directly fetches the blocks to download from the quarantine which solves both problems (the quarantine already de-duplicates and is clean of stale information). Removing the queue for blobs is left for a future PR. Co-authored-by: tersec <tersec@users.noreply.github.com>

Validator monitoring (#2925) Validator monitoring based on and mostly compatible with the implementation in Lighthouse - tracks additional logs and metrics for specified validators so as to stay on top on performance. The implementation works more or less the following way: * Validator pubkeys are singled out for monitoring - these can be running on the node or not * For every action that the validator takes, we record steps in the process such as messages being seen on the network or published in the API * When the dust settles at the end of an epoch, we report the information from one epoch before that, which coincides with the balances being updated - this is a tradeoff between being correct (waiting for finalization) and providing relevant information in a timely manner)
