> 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.
