> ClientCnxn.java logs errors during watcher removal:
> LOG.error("Failed to find watcher!", nwe);
> LOG.error("Exception when removing watcher", ke);
> An error code/exception is generated so the logs are noisy and unnecessary.
> If the client handles the error there's still a log message. This is
> different than other APIs. These logs should be removed.
