    Description

      Currently UnassignProcedure returns success when server carrying a region is NOT online. Assumption here is that ServerCrashProcedure will handle splitting logs etc for these regions. When UnassignProcedure completes, MoveRegionProcedure resumes with AssignProcedure. AssignProcedure can some times assign regions without pre-requisite steps (done either by UnassignProcedure or ServerCrashProcedure). Fix is to fail UnassignProcedure and parent MoveRegionProcedure if source server is not online.
