      Description

      BlockCommitSequenceId will be increasing long value generated in the Ratis leader for every commit operation of a block and will be replicated over to the followers. This id will be updated in OM and will be reported to SCM which will help the most consistent copy of a open container replica in case the majority of the datanodes fail.

      The blockCommitSequenceId is same as the commit index of the flush(PUT_BLOCK) transaction in Ratis.
