      Description

      It is possible that the reportRegionStateTransition method is succeeded at master side, but before returning the the region server, the rpc connection is broken, or the master restarts. So next when the region server try again,we will find that the state for the region and the TRSP is not correct, and can lead to a RS abort or something even worse.

      We should be able to determine whether a reportRegionStateTransition call is just a retry and has already been succeeded, and just ignore it.
