- Kubeadm: when adding new control plane nodes with "kubeadm join", ensure that the etcd member addition is performed only if a given member URL does not already exist in the list of members. Similarly, on "kubeadm reset" only remove an etcd member if its ID exists.

- Fixed an incorrect reference to `JoinConfigurationKind` in the error message when no ResetConfiguration is found during `kubeadm reset` with the `--config` flag. ([#132258](https://github.com/kubernetes/kubernetes/pull/132258), [@J3m3](https://github.com/J3m3)) [SIG Cluster Lifecycle]

This means that now, if you set a value in a context variable before `yield`, the value would still be available after `yield` (as you would intuitively expect). And it also means that you can reset the context variable with a token afterwards.

For example, this works correctly now:

```Python
from contextvars import ContextVar
from typing import Any, Dict, Optional
