Added Coordinated Leader Election as Alpha under the `CoordinatedLeaderElection` feature gate. With the feature enabled, the control plane can use LeaseCandidate objects (coordination.k8s.io/v1alpha1 API group) to participate in a leader election and let the kube-apiserver select the best instance according to some strategy.

The StorageProtection feature, which prevents deletion of PVCs while Pods are still using them and of PVs while still bound to a PVC, is now generally available, and volume resizing, which lets you increase size of a volume after a Pod restarts is now beta, which means it is on by default.

New alpha features include:

- Fix PermissionDenied issue on SMB mount for Windows ([#99550](https://github.com/kubernetes/kubernetes/pull/99550), [@andyzhangx](https://github.com/andyzhangx))

  By explicitly comparing the value to true, we let type-checking see the result will be a boolean,
