Reason:
Some networks have no much archive peers, also ConsensusLayer clients are not-good(not-incentivised) at serving history.
more files(shards) - means "more metadata", "more lookups for non-indexed queries", "more dictionaries", "more bittorrent connections", ...
less files - means small files will be removed after merge (no peers for this files).
ToDo:
[x] Recent 500K - merge up to 100K
[x] Older than 500K - merge up to 500K
[x] Start seeding 100k files
[x] Stop seeding 100k files after merge (right before delete)
In next PR:
