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.

When privileged is enabled for a container, all the `/dev/*` block
devices from the host are mounted into the guest. The
`privileged_without_host_devices` flag prevents host devices from
being passed to privileged containers.

According to [etcd's docs](https://etcd.io/docs/v3.4.0/op-guide/configuration/#--log-package-levels), argument 'log-package-levels' should not contain underscores.

Using `kubeadm init phase kubeconfig all` breaks kubelet client certificate rotation
as we are missing `kubeadm init phase kubelet-finalize all` to point to `kubelet-client-current.pem`

kubeconfig format is stable so let's just use lineinfile,
this will avoid other future breakage

This revert to the logic before 6fe22483
