- If the user specifies an invalid timeout in the request URL, the request will be aborted with an HTTP 400.

When writing the ConfigMap kubeadm (init, upgrade apply) will respect the value of UnversionedKubeletConfigMap, while when reading it (join, reset, upgrade), it would attempt to use new format first and fallback to the legacy format if needed.
