test: older_openshift_fail.yml fails with py3.7+

[goneri]

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).

Can we get this one merged?

@geerlingguy and I were discussing this and think the test can just be nuked. It served its purpose, but now it's checking for something rather old.

[geerlingguy]

Yeah—it was 2018 when the last major release of 0.6.x came out. We're still testing for a bug (that I remember from then) that's been resolved for over two years of new releases...

I believe either @willthames or @fabianvf originally wrote that test though, and might have more missing context—it might be nice to get one final "yes" from one of them before totally nuking it though.

I'm going to merge this for now, but as mentioned earlier and in #300 we'd like to remove this test entirely.
