--- 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
