Ch4 (cluster-local-vms) - Testing the cluster with a deployment using Ansible [SOLUTION]

Task "Create hello-k8s resources and wait until they are Ready." fails due to a bug in Python openshift 0.12: https://github.com/kubernetes-client/python/issues/1333

Error:

The full traceback is:
Traceback (most recent call last):

...

    "msg": "MODULE FAILURE\nSee stdout/stderr for the exact error",
    "rc": 1
}

This can be solved by setting the openshift version in the test-deployment pre_task:

  pre_tasks:
    - name: Ensure k8s module dependencies are installed.
      pip:
        name: openshift==0.11.0
        state: present

@adelerhof - According to this issue (https://github.com/ansible-collections/community.kubernetes/issues/314), if you update Ansible to the latest version (2.9.17 or later or the latest 3.x version), then the problem should be resolved as well.
