> This test starts a cluster, then starts the ZKFCs, then tries to issue a manual failover.
But, it doesn't wait until the ZKFCs are fully done starting up. So, I see a test run occasionally
fail because the failover says that the NN is not ready yet. The test just needs to wait until
the ZKFCs are in "healthy" state before proceeding.
