During cluster delection, the finalizer will not be removed until all the PVCs are removed. Since this could wait for a long time, as long as the deletion event is re-queued, we need to cancel the goroutine that is watching for cluster deletion so it can avoid running multiple goroutines as the event runs again and again.
