    Standardise Workflow messaging and optionally persist messages

    This workflow captures the boilerplate that is copied and pasted for Zaqar
    messages. It also adds the ability to persist the messages in Swift.

    This can be manually tested with:

        $ cat input.json
        {
            "type": "test",
            "queue_name": "tripleo",
            "plan_name": "overcloud",
            "execution": {
                "id": "UUID"
            }
        }
        $ openstack workflow execution create tripleo.messaging.v1.send input.json
