change coredns image name to `coredns/coredns` and prefix `v` to tag (#7570)
follow new naming conventions for gcr's coredns image.
starting from 1.21 kubeadm assumes it to be `coredns/coredns`:
this causes the kubeadm deployment being unable to pull image, beacuse `v`
was also added in image tag, until the role `kubernetes-apps` ovverides
it with the old name, which is only compatible with <=1.7.

Backward comptability with kubeadm <=1.20 is mantained checking
kubernetes version and falling back to old names (`coredns:1.xx`) when
the version is less than 1.21

Add KubeSchedulerConfiguration for k8s 1.19 and up (#7351)
* Add KubeSchedulerConfiguration for k8s 1.19 and up

With release of version 1.19.0 of kubernetes KubeSchedulerConfiguration
was graduated to beta. It allows to extend different stages of
scheduling with profiles. Such effect is achieved by using plugins and
extensions.

This patch adds KubeSchedulerConfiguration for versions 1.19 and later.
Configuration is set to k8s defaults or to kubespray vars. Moving those
defaults to new vars will be done in following patch.

Replace kube-master with kube_control_plane (#7256)
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.
