cinder-tempest-plugin CG tests are broken

[Alan Bishop]

I suspect the CG tests have been broken for a while, mainly because a limited number of drivers support the feature. The first failure is this:

==============================
Failed 1 tests - output below:
==============================

setUpClass (cinder_tempest_plugin.api.volume.test_consistencygroups.ConsistencyGroupsV2Test)

This source of problem was traced to [1].

It's easy to fix by adding admin to the list of credentials (credentials = ['primary', 'admin']) but that exposes the next layer of failure. Tests run, but all fail with this:

I think we don't need these tests for consistencygroups any more. Consistencygroups APIs are deprecated. These tests can be removed.

We have tempest tests for generic volume groups.
