first batch of work towards the VC/BN split: - we have a new binary which connects via RPC to the respective BN and has an internal clock - waking it up on every slot - the BN has a new option called --external-validators and currently in order to have the VC binaries to run we need to pass EXTERNAL_VALIDATORS=yes to make - factored some code out of beacon_node.nim for easier reuse in validator_api.nim and validator_client.nim - the VC loads its associated private keys from the datadir for its BN - most of the validator API calls have been implemented as a stub. - the VC polls its BN at the start of each epoch - getting a list of all active validators for the current epoch - and then continues to request blocks and sign them with its appropriate validators when necessary

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)

Bump modules to take advantage of the new Json format flavors support Since quite a lot of additional procs were now compiled as generics, this lead to compiler bugs that had to be worked-around: * The `Domain` type was renamed to `Eth2Domain` to avoid compilation errors due to conflicts with `nativesockets.Domain`.

singe validator key cache Instead of keeping a validator key list per EpochRef, this PR introduces a single shared validator key list in ChainDAG, and cleans up some other ChainDAG and key-related issues. The PR does not introduce the validator key list in the state transition - this is because we batch-check all signatures before entering the spec code, thus the spec code never hits the cache. A future refactor should _probably_ remove the threadvar altogether. There's a few other small fixes in here that make the flow easier to read: * fix `var ChainDAGRef` -> `ChainDAGRef` * fix `var QuarantineRef` -> `QuarantineRef` * consistent `dag` variable name * avoid using threadvar pubkey cache in most cases * better error messages in batch signature checking

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)
