In changes 12f7345, c2fb9b0, 6051a74, c7b01eb and ab946c4 Mistral Workflows were marked as failed if they sent a Zaqar message with the status "FAILED". This is correct, but it turns out there is an easier way to do it. Mistral has a engine command designed for this purpose, using it removes some of the duplication we have incurred. We use on-success rather than on-complete to surface the best error on the workflow. If the Zaqar queue post fails, then the workflow will fail with this error. If, on-complete we then manually mark the workflow as failed it will ovrwrite the Zaqar error with a generic one.
