Ansible v2.9 and v2.10 are EOL as [1].
This drops those version supports by following the upstream Ansible.

This sets use_ssh_args true always because that is required to use
ssh_args on ansible.cfg on Ansible v2.11 or later[2].

ansible_ssh_host is replaced with ansible_host because ansible_ssh_host
has been deprecated already and cenots7 jobs were failed due to the
deprecated ansible_ssh_host.

As a step of release process, this updates KUBESPRAY_VERSION.
Thank you so much for creating and pushing container images of
the new version floryut !

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.
