This PR makes the necessary adjustments to deal with the revamped snappy
API.
In practical terms for nimbus-eth2, there are performance increases to
gossip processing, database reading and writing as well as era file
processing. Exporting `.era` files for example, a snappy-heavy
operation, almost halves in total processing time:
Pre:
```
Average, StdDev, Min, Max, Samples, Test
39.088, 8.735, 23.619, 53.301, 50, tState
237.079, 46.692, 165.620, 355.481, 49, tBlocks
```
Post:
```
All time are ms
Average, StdDev, Min, Max, Samples, Test
25.350, 5.303, 15.351, 41.856, 50, tState
141.238, 24.164, 99.990, 199.329, 49, tBlocks

* Add `NoMonitor` flag to stop SyncManager from monitoring sync situation.
* Remove `toleranceValue` and `PeerScoreHeadTooNew`.
Co-authored-by: Etan Kissling <etan@status.im>
* `gnosis-chain` -> `gnosis`
Use same name as LH/Teku throughout
* fixes#3504
* fixes large stack temporary that can cause crashes during genesis
detection
Some upstream repos still need fixes, but this gets us close enough that
style hints can be enabled by default.
In general, "canonical" spellings are preferred even if they violate
nep-1 - this applies in particular to spec-related stuff like
`genesis_validators_root` which appears throughout the codebase.
Validator monitoring improves logging by giving more specific monitoring
information, and can now be seen as complete.
Previously, logging has focused on "Attestation sent" messages which
carry little informational value when things go wrong, and are overly
aggressive when everything works as expected (sending attestations is
the norm).
* lower "Attestation sent" log to `INFO`
* mark 1.7.0 as the start of the validator monitor feature - previous
versions had significant bugs in totals mode
The `pyrmont` testnet has been discontinued.
For experiments, it's still possible to run pyrmont nodes by passing a
genesis/config, but this PR removes the bundled `--network:pyrmont`
option.
* update docs
* remove empty docs
* remove obsolete `eth2-stats` page
rocksdb was never actually used in nimbus-eth2 and existed only to satisfy nim-eth dependencies for test running - these have since moved to nimbus-eth1.
* bump nim-eth
`.era` files and Req/Resp protocols use framed formats - aligning the
database with these makes for less recompression work overall as gossip
is sent only once while req/resp repeats (potentially) - this also
allows efficient pruning-to-era where snappy-recompression is the major
cycle thief.
