Replace kube-master with kube_control_plane (#7256)

Browse Source 
This replaces kube-master with kube_control_plane because of [1]:

  The Kubernetes project is moving away from wording that is
  considered offensive. A new working group WG Naming was created
  to track this work, and the word "master" was declared as offensive.
  A proposal was formalized for replacing the word "master" with
  "control plane". This means it should be removed from source code,
  documentation, and user-facing configuration from Kubernetes and
  its sub-projects.

NOTE: The reason why this changes it to kube_control_plane not
      kube-control-plane is for valid group names on ansible.

Then run the playbook with ```--limit etcd,kube-master``` and increase the number of ETCD retries by setting ```-e etcd_retries=10``` or something even larger. The amount of retries required is difficult to predict.

When finished you should have a fully working control plane again.
