test auth_file_propagation should be removed

[Joshua Genet]

As seen here: https://solutions.qa.canonical.com/testruns/testRun/b9c16068-5ce4-408a-a5a8-47d1424964e4

Right now when this test fails, it is hard to tell what went wrong. The only way that I can see to triage failures would be to look at the /root/cdk/basic_auth.csv on each of the kubernetes-master nodes. It would be useful if the test was a bit more verbose.

Here's the output and how we are running it:

Honestly, this test seems kinda silly now given that Kubernetes no longer supports Basic Auth. The kubernetes-master charm still dutifully propagates the basic_auth.csv file, but for no real reason.

I think we should just remove this test.

[Joshua Genet (genet022)]

Oh snap yeah, removed since 1.19.
I'm all for not running this. I'll remove it on our end.
Thanks!
