| Merged ``RbacUtils`` and ``RbacUtilsMixin`` classes. Now there is only |
| ``RbacUtilsMixin`` class. The new class still provides all functionality of |
| the original ``RbacUtils`` class. New implementation simplifies the usage |
| * there is no need in calling ``cls.setup_rbac_utils()`` function, because |
| it happens automatically at the ``setup_clients`` step. |
| * there is no ``rbac_utils`` variable, so if you need to call a |
| ``override_role`` function, just do it using ``self``: |
| with self.override_role(): |
| * there is no need in ``test_obj`` variable for ``override_role`` function, |
| because it can use ``self``. |
| - Remove usage of ``cls.setup_rbac_utils()`` function. |
| Remove usage of ``self.rbac_utils`` variable: |
| with self.rbac_utils.override_role(self): |
| with self.override_role(): |
| Remove ``test_obj`` in usage of ``override_role`` context manager: |
| with self.override_role(self): |
| with self.override_role(): |
