> As CommitContext contains a sequenceId, it will auto-increment per operation, In HA environment,
we should make it work, also add a distributed counter
> * Add CommitContextFactory , use getCommitContext(UUID serverUUID, long sequenceId) in
the factory instead of new CommitContext(UUID serverUUID, long sequenceId)
> * counter.getGlobalSequenceId() will return the Global sequence id
