ts feature gate. It can be used to tell kubeadm to wait for all control plane components to be ready when running "kubeadm init" or "kubeadm join --control-plane". Currently kubeadm only waits for the kube-apiserver. The "kubeadm join" workflow now includes a new experimental phase called "wait-control-plane". This phase will be marked as non-experimental when WaitForAllControlPlaneComponents becomes GA. Accordingly a "kubeadm init" phase "wait-control-plane" will also be available once WaitForA...

* Kubeadm now includes CoreDNS version 1.6.5 ([#85108](https://github.com/kubernetes/kubernetes/pull/85108), [@rajansandeep](https://github.com/rajansandeep))
    *  - `kubernetes` plugin adds metrics to measure kubernetes control plane latency.
    *  -  the `health` plugin now includes the `lameduck` option by default, which waits for a duration before shutting down.
