> We need new implementation of snapshot feature that is more robust and performant.  Ideally,
it will work with multiple tables as well. The possible areas of improvements:
> #  Must be flushless. Coordinated memstore flushes across a cluster are bad.
> #  Verification phase must be distributed, done in parallel and not on Master.
> In theory, the only info we need to record snapshot of a table: list of WAL files, list
of HFiles and max sequence id of an edit which has been flushed per Region.
