Sorry for the delay, got stuck with company work.
I have attached the patch.

Added a new RS observer, ReplicationObserver to solve this bug.
Please review.

> Currently the support for replication of bulk loaded hfiles relies on bulk load marker written in the WAL.
> The move of bulk loaded hfile(s) (into region directory) may succeed but the write of bulk load marker may fail.
> This means that although bulk loaded hfile is being served in source cluster, the replication wouldn't happen.
> Normally operator is supposed to retry the bulk load. But relying on human retry is not robust solution.
