      Description

      In our ITBLL test we observer a race between the SCP and TRSP which causes a region being assigned to two region servers.

      Not fully understand the scenario, but anyway, the we do not consider the situation in the old code, that after SCP gets the region list of a dead server, there could still be a reportRegionStateTransition call from dead server and mess up things.

      In general, I think we should have a fence in the AssignmentManager to prevent the reportRegionStateTransition from the dead servers to mess up the states.
