Implied roles API tests

Implied roles is a feature added recently to keystone. It enables the
possibility to have roles implying another roles, this avoids the need
to add specific role assignments to each action a user can take. For
example: if we had the "admin" role implying the "member" role, we
would not need to add entries specifiying the "member" role for a
user that is already "admin".
