ZKFailoverController doesn't handle failure to become active correctly

Details

    Description

      The ZKFC doesn't properly handle the case where the monitored service fails to become active. Currently, it catches the exception and logs a warning, but then continues on, after calling quitElection(). This causes a NPE when it later tries to use the same zkClient instance while handling that same request. There is a test case, but the test case doesn't ensure that the node that had the failure is later able to recover properly.
