- Implemented alpha support for a drop-in kubelet configuration directory. ([#119390](https://github.com/kubernetes/kubernetes/pull/119390), [@sohankunkerkar](https://github.com/sohankunkerkar))

* Rename `--cgroups-per-qos` to `--experimental-cgroups-per-qos` in Kubelet ([#36767](https://github.com/kubernetes/kubernetes/pull/36767), [@vishh](https://github.com/vishh))
* Implement CanMount() for gfsMounter for linux ([#36686](https://github.com/kubernetes/kubernetes/pull/36686), [@rkouj](https://github.com/rkouj))

```

...before this change it would raise an error when resetting the context variable, because the `contextvars` context was different, because of the way it was implemented.

**Note**: You probably don't need `contextvars`, and you should probably avoid using them. But they are powerful and useful in some advanced scenarios, for example, migrating from code that used Flask's `g` semi-global variable.

	// policies and any (LDAP user created) service accounts on the other
	// peer clusters, and if so, reject the cluster replicate add request.
	// This is not yet implemented.

	// VALIDATIONS COMPLETE.

	// Create a common service account for all clusters, with root
	// permissions.

	// Create a local service account.

* Extends the VolumeSubpathEnvExpansion alpha feature to support environment variable expansion ([#71351](https://github.com/kubernetes/kubernetes/pull/71351), [@kevtaylor](https://github.com/kevtaylor))
    * Implements subPathExpr field for expanding environment variables into a subPath
    * The fields subPathExpr and subPath are mutually exclusive
    * Note: This is a breaking change from the previous version of this alpha feature
