Description

The ZKFC code wasn't previously terminating the ZK connection in all cases where it should (eg after a failed startup or after formatting ZK). This didn't cause a problem for CLI usage, since the process exited afterwards, but caused the test results to get clouded with a lot of "Reconecting to ZK" messages, which make the logs hard to read.
