Older openshift test cases are no longer valid for this
collection. Removing them for now.
Fixes: #300
Signed-off-by: Abhijeet Kasurde <akasurde@redhat.com>
The `older_openshift_fail.yml` test playbook fails with Python 3.7 because the old `kubernetes.client.apis.admissionregistration_api` module uses the new `async` keyword as a function parameter name. From: https://docs.python.org/3/whatsnew/3.7.html
Backwards incompatible syntax changes:
`async` and `await` are now reserved keywords.
In this case, we get a `SyntaxError` exception instead of the expected `Failed to import the required Python library (openshift >= 0.7.2)`.
