HBASE-26984 Chaos Monkey thread dies in ITBLL Chaos GracefulRollingRestartRsAction (#4383) 

There are two cases here:
  1. Chaos Monkey thread died and there is no chaos after that.
  2. Sometimes, regions are being moved back too quick that region server has not finished its initliazation yet.
     wait sometime to make sure that region server finishes its initialization.
