Looking at the test code [0], it looks like glance throws a different error than what the test expects as reason for not to be able to delete the namespace. I think this may also be a case of incorrect keystone policy.

It looks like the test runner might be on jammy; try it on focal, as upstream haven't transited to jammy yet (but they are starting to test tempest on it)
