  - `create poddisruptionbudget` ([#36646](https://github.com/kubernetes/kubernetes/pull/36646), [@kargakis](https://github.com/kargakis))
  - `create clusterrole` ([#41538](https://github.com/kubernetes/kubernetes/pull/41538), [@xingzhou](https://github.com/xingzhou))

* The `--bootstrap-kubeconfig` argument to Kubelet previously created the first bootstrap client credentials in the certificates directory as `kubelet-client.key` and `kubelet-client.crt`.  Subsequent certificates created by cert rotation were created in a combined PEM file that was atomically rotated as `kubelet-client-DATE.pem` in that directory, which meant clients relying on the `node.kubeconfig` generated...

- The `kubectl debug` is able to create ephemeral containers in pre-1.22 clusters with the `EphemeralContainers` feature enabled. Note that versions of kubectl prior to 1.22 are unable to create ephemeral containers in clusters version 1.22 and greater due to an API change.

This removes the cloud-provider role and role binding from the rbac boostrapper and replaces it with a policy applied via addon mgr. This also creates a new clusterrole allowing the service account to create events for any namespace.

* client-go: alpha support for out-of-tree exec-based credential providers. For example, a cloud provider could create their own authentication system rather than using the standard authentication provided with Kubernetes. ([#59495](https://github.com/kuber...
