- Kubeadm: fixes a preflight check that can fail hostname construction in IPV6 setups ([#134589](https://github.com/kubernetes/kubernetes/pull/134589), [@liggitt](https://github.com/liggitt)) [SIG API Machinery, Auth, Cloud Provider, Cluster Lifecycle and Testing]

 - Kubeadm: increase robustness for "kubeadm join" when adding etcd members on slower setups ([#90645](https://github.com/kubernetes/kubernetes/pull/90645), [@neolit123](https://github.com/neolit123)) [SIG Cluster Lifecycle]

    * kubeadm upgrade now successfully upgrades etcd and the controlplane to use TLS
    * kubeadm upgrade now supports external etcd setups
    * kubeadm upgrade can now rollback and restore etcd after an upgrade failure

The kube-scheduler is adding a new, simplified config field for Plugins to allow multiple extension points to be enabled in one spot.
The new `multiPoint` plugin field is intended to simplify most scheduler setups for administrators.
Plugins that are enabled via `multiPoint` will automatically be registered for each individual extension point that they implement.

- Kubeadm: remove the "ephemeral_storage" request from the etcd static pod that kubeadm deploys on stacked etcd control plane nodes. This request has caused sporadic failures on some setups due to a problem in the kubelet with cadvisor and the LocalStorageCapacityIsolation feature gate.
