// TODO remove after 1.32 release
// add control-plane role for all master nodes over master node group
// At current moment, first bootstrapped master get 'control-plane' role,
// but other master nodes don't get this role, because
// first master bootstrapped with kubeadm (kubeadm set role to node over label), but
// master node group was created on bootstrap does not contain label with role
// we will add label to nodegroup template for existing clusters
