Jacek Sieka 76f15302a7 better timesharing in eth2 processor
* use `idleAsync` to more evenly divide cpu attention when syncing in
particular - this gives networking better latency
* more strict exception handling in eth2_processor

[WIP] skeleton of attester slashing pool & validators (#1639)
* skeleton of attester slashing pool & validators

* add skeleton for proposer slashings and voluntary exits; rename pool to more inclusive exit pool to stay consistent with all three; ensure is initialized by beacon_node so is safe to merge, even if it doesn't do much yet

implement clock disparity for attestation validation (#1568)
This implements disparity, resolving a part of
https://github.com/status-im/nim-beacon-chain/issues/1367

* make BeaconTime a duration for fractional seconds
* factor out attestation/aggregate validation
* simplify recording of queued attestations
* simplify attestation signature check
* fix blocks_received metric
* add some trivial validation tests
* remove unresolved attestation table - attestations for unknown blocks
are dropped instead (cannot verify their signature)

Fork choice - almost free pruning - fix #1534 (#1535)
* initial - cheaper pruning - addresses  #1534

* Pass tests: update offset when pruning, proper handling of pruned parents

* Use options instead of nil for nilable newHead (finalization passing but rootcause not solved)

* First line of defense against stackoverflow in tests

* Fix compute_delta offset after pruning

* Rebase fix - medalla ready

* Remove Option[BlockRef]

Jacek Sieka 22998fdfd4 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
