Fail the plan_management workflows when sending a "FAILED" message

When Mistral workflows execute a second workflow (a sub-workflow
execution), the parent workflow can't easily determine if sub-workflow
failed.  This is because the failure is communicated via a Zaqar message
only and when a workflow ends with a successful Zaqar message it appears
have been successful. This problem surfaces because parent workflows
should have an "on-error" attribute but it is never called, as the
workflow doesn't error.

This change marks the workflow as failed if the message has the status
"FAILED". Now when a sub-workflow fails, the task that called it should
have the on-error triggered. Previously it would always go to
on-success.
