- Kubeadm: only enable the klog flags that are still supported for kubeadm, rather than hiding the unwanted flags. This means that the previously unrecommended hidden flags about klog (including `--alsologtostderr`, `--log-backtrace-at`, `--log-dir`, `--logtostderr`, `--log-file`, `--log-file-max-size`, `--one-output`, `--skip-log-headers`, `--stderrthreshold`...

 *  * [onData] (optional sequence of data frames)
 *
 * As a stream ID is scoped to a single HTTP/2 connection, implementations which target multiple
 * connections should expect repetition of stream IDs.
 *
 * Return true to request cancellation of a pushed stream.  Note that this does not guarantee
 * future frames won't arrive on the stream ID.
