- Kubeadm: When adding an etcd peer to an existing cluster, if an error is returned indicating the peer has already been added, this is accepted and a `ListMembers` call is used instead to return the existing cluster. This helps to diminish the exponential backoff when the first AddMember call times out, while still retaining a similar performance when the peer has already been added from a previous call.

unschedulable pods, scale up is required and cloud provider is slow to set up networking for new nodes.
Anyway, the cluster should get back to the proper size after 10 min.

### Deployment

- Kubeadm: remove the deprecated "kubeadm alpha kubelet config enable-dynamic" command. To continue using the feature please defer to the guide for "Dynamic Kubelet Configuration" at k8s.io. This change also removes...

- Kubeadm: avoid panicing if the user has malformed the kubeconfig in the cluster-info config map to not include a valid current context. Include proper validation at the appropriate locations and throw errors instead. ([#134723](https://github.com/kubernetes/kubernetes/pull/134723), [@neolit123](https://github.com/neolit123)) [SIG Cluster Lifecycle]

- Kubeadm: print all the kubelets and nodes that need to be upgraded...
