- Kubeadm: do not upload kubelet patch configuration into `kube-system/kubelet-config` ConfigMap ([#123106](https://github.com/kubernetes/kubernetes/pull/123106), [@SataQiu](https://github.com/SataQiu)) [SIG Cluster Lifecycle]

## Dependencies

  
  - `apiserver_encryption_config_controller_automatic_reload_failures_total`: Total number of failed automatic reloads of encryption configuration.
  - `apiserver_encryption_config_controller_automatic_reload_success_total`: Total number of successful automatic reloads of encryption configuration.

* `cluster/gke` has been removed. GKE end-to-end testing should be done using `kubetest --deployment=gke` ([#50338](https://github.com/kubernetes/kubernetes/pull/50338), [@zmerlynn](https://github.com/zmerlynn))
* kubeadm: Upload configuration used at 'kubeadm init' time to ConfigMap for easier upgrades ([#50320](https://github.com/kubernetes/kubernetes/pull/50320), [@luxas](https://github.com/luxas))

- kube-apiserver now reloads the `--authorization-config` file when it changes. Reloads increment the `apiserver_authorization_config_controller_automatic_reload_last_timestamp_seconds` timestamp metric, with `status="success"` for successful reloads and `status="failed"` for failed reloads. Failed reloads keep using the previously loaded authorization configuration.
