Add support for deterministic database shards (#2688):

Browse Source 
Add support to allow multiple indepedent nodes to produce a binary identical
shard for a given range of ledgers. The advantage is that servers can use
content-addressable storage, and can more efficiently retrieve shards by
downloading from multiple peers at once and then verifying the integrity of
a shard by cross-checking its checksum with the checksum other servers report.
