From kube v1.24 onwards, Kubeadm applies a "node-role" label to its
control plane Nodes.Currently this label key is node-role.kubernetes.io/master
and it will be renamed to node-role.kubernetes.io/control-plane. Kubeadm
also uses the same "node-role" as key for a taint it applies on control
plane Nodes. This taint key should also be renamed to
"node-role.kubernetes.io/control-plane".
