std/osproc,
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

avoid double deserialization When blocks and attestations arrive, they are SSZ-decoded twice: once for validation and once for processing. This branch enqueues the decoded block directly for processing, avoiding the second, slow deserialization. * move processing of blocks and attestations to queue * ...and out from beacon_node * split attestation processing into attestations and aggregates * also updates metrics * clean up logging to better follow the lifetime of gossip: arrival, validation and processing * drop attestations and aggregates if there are too many * try to prioritise blocks and aggregates before single-validator attestations
