      Description

      While going throw TestZKRMStateStorePerf class , found that we are not initializing variable TestingServer curatorTestingServer if real zookeeper cluster are passed to utility. But down the line , this variables are used which causes NPE

      I tested by passing program arguments which result in NPE
