erigon2: fix linter

Problem:
QuerySeeds will poke 150 random entries in the whole node DB and ignore hitting "field" entries.
In a bootstrap scenario it might hit hundreds of :lastping :lastpong entries,
and very few true "node record" entries.
After running for 15 minutes I've got totalEntryCount=1508 nodeRecordCount=114 entries.
There's a 1/16 chance of hitting a "node record" entry.
It means finding just about 10 nodes of 114 total on average from 150 attempts.

Solution:
Split "node record" entries to a separate table such that QuerySeeds doesn't do idle cycle hits.

UpdateFindFails/UpdateLastPingReceived/UpdateLastPongReceived events
are causing bursty DB commits (100 per minute).

This optimization throttles the disk writes to happen at most once in a few seconds,
because this info doesn't need to be persisted immediately.

This helps on HDD drives.

Revert "Prevent frequent commits to the node DB in sentries (#2505)".
This reverts commit 65a9a265.

The command builds were always using the root go.mod.
Adding cmd/mycmd/go.mod produced an "package not found" error.

This changes the build to run in the cmd/mycmd directory:
* If cmd/mycmd/go.mod is present, it is used.
* Otherwise it builds the main package using the root go.mod as before.

Encode and hash logic was duplicated in multiple places.
* Move encoding to p2p/discover/v4wire
* Move hashing to p2p/enode/idscheme

* Change newRandomLookup to create a proper random key on a curve.

* get chain config, genesis hash and network ID by chain name in params/config

* Bump storage space recommendation to 4TB.

* OK, 3TB instead of 4TB

* SSD performance deteriorates when close to capacity
