Previously, TestAuthExternalDomain was inheriting from test_v3.RestfulTestCase,
which allowed it to run as part of the keystone test suite. This commit breaks
it into a class that only inherits from `object` and introduces 3 other classes
the inherit the old TestAuthExternalDomain and run the tests according to the
setup needed.
Since the Fernet provider doesn't support bind authentication, there is no test
class to setup Fernet and run the TestAuthExternalDomain behaviors. This change
will make defaulting to Fernet easier.
This fix was originally a part of https://review.openstack.org/#/c/258650 but
this is an attempt to break 258650 into smaller, more reviewable, pieces.
