Remove auth_version config from get_credentials

In preparation for migration to tempest-lib, add a new parameter
to get_credentials to specify the identity version.
Define a wrapper cred_provider.get_credentials that exposes
the same signature auth.get_credetials use to have, and switch
all consumers to use the cred_provider version.
Do not raise InvalidConfiguration from auth module.
Adapt unit tests accordingly, and remove their dependency to
fake configs, to prepare them as well for migration to tempest-lib.
