Comment 5 for bug 1296955

I started debugging with all admin setting as None in tempest.conf and no tenant isolation. The biggest problem right off the bat is that there is inconsistency between the kinds of exceptions that are raised in different places that are encountered in the various ways we check for admin creds. Some of those places know they are checking admin creds and some are generic, usually raising ConfigurationError. The admin skip places are looking for NotImplementedError.

In any event we should be changing the try/except logic to check for admin with explicit use of is_admin_available.
