Cross-namespace template processing is not being tested

These commented out tests https://github.com/openshift/origin/blob/master/test/extended/testdata/cmd/test/cmd/templates.sh#L130-L149 are problematic, because they are testing rather important functionality of cross-namespace template processing.

This problem recently escalated after landing k8s 1.25, where there was a suspicion that new version of kube-apiserver removed that functionality. We need to bring back this test, as well as similar tests which are touching logging in functionality. https://github.com/openshift/origin/blob/master/test/extended/testdata/cmd/test/cmd/authentication.sh is another similar test being skipped due to similar reasons.

Based on my search: https://github.com/openshift/origin/blob/master/test/extended/oauth/helpers.go#L18 we could deploy Basic Auth Provider ie. password based, and group all tests relying on this functionality under a single umbrella.

The biggest question to answer is how we can properly deal with multiple IdentityProviders, so I'd suggest reaching out to Auth team for help.

The second problem that was identified is various cloud providers, so we've agreed to run this test initially only on AWS and GCP.
