Description

HDDS-3476 used the transaction info persisted in OM DB during double buffer flush when OM is restarted. This transaction info log index and the term are used as a snapshot index. So, we can remove the replay logic from actual request logic. (As now we shall never have the transaction which is applied to OM DB will never be again replayed to DB)
