* The kube-discovery Deployment isn't used anymore when creating a kubeadm cluster and shouldn't be used anywhere else either due to its insecure nature.
* The Certificates API has graduated from alpha to beta. This is a backwards-incompatible change since the alpha support is dropped, and therefore kubeadm v1.5 and v1.6 don't work together (for example kubeadm v1.5 can't join a kubeadm v1.6 cluster).
