upgrade:
  - |
    The old deprecated ``keymgr`` options have been removed.
    Configuration options using the ``[keymgr]`` group will not be
    applied anymore. Use the ``[key_manager]`` group from Castellan instead.
    The Castellan ``api_class`` options should also be used instead, as most
    of the options that lived in Nova have migrated to Castellan.

    - Instead of ``api_class`` option ``nova.keymgr.barbican.BarbicanKeyManager``,
      use ``castellan.key_manager.barbican_key_manager.BarbicanKeyManager``
    - Instead of ``api_class`` option ``nova.tests.unit.keymgr.mock_key_mgr.MockKeyManager``,
      use ``castellan.tests.unit.key_manager.mock_key_manager.MockKeyManager``
    - ``nova.keymgr.conf_key_mgr.ConfKeyManager`` still remains, but the ``fixed_key``
      configuration options should be moved to the ``[key_manager]`` section
