This commit fixes a possible panic in the cluster External Audit watcher that can occur whenever the underlying backend watcher closes unexpectedly, and resulted in a double-close of the `initialized` channel. This fix here is to switch from closing an "initialized" channel whenever a watcher is initialized, to periodically writing to a "running" channel during the events watch loop, whenever there is a listener waiting on the channel. This is what some other watchers (e.g. HeadlessAuthenticationWatcher) already do, and allow for the test to wait for the new watcher to init after simulating a failed watcher. Changelog: Fixed potential panic after backend watcher failure.
