> The tests have become flaky bcoz once  nodes are shutdown inn Ratis pipeline, a watch request can either be received at server at a server and fail with NotReplicatedException or sometimes it fails with StatusRuntimeExceptions from grpc which both need to be accounted for in the tests. Other than that, HDDS-1384 also causes bind exception to e thrown intermittently which in turn shuts down the miniOzoneCluster. To overcome this, the test class has been refactored as well.
