Constructing a Broadcaster already starts a watch which runs in the background. Shutdown must be called to avoid leaking the goroutine. Providing a context was supposed to remove the need to call Shutdown, but that did not actually work because the logic for "must check for cancellation" was accidentally inverted. While at it, structured log output also gets tested together with checking for goroutine leaks. Kubernetes-commit: ff779f1cb56cf896405e52f7923188b99b88bb00
