Test olso_messaging settings changes in integration tests

Test the migration of settings from

oslo_messaging_settings
   rabbit_transient_quorum_queue: false
   rabbit_stream_fanout: false

to

oslo_messaging_settings
   rabbit_transient_quorum_queue: true
   rabbit_stream_fanout: true

inside integration tests for all Openstack services that use oslo_messaging, followed by a rolling restart of all AMQP statefulsets. This test scenario was added due to a bug inside the previous oslo.messaging patch. The test for the setting migration can be removed with the next YAOOK release while the rolling restart test case should be kept in the future.
