 Once the above `Workflow Restarter TEST` is working then you should be able to add the workflow restarter to any of your existing github workflows.  The key is to re-use the `on-failure-workflow-restarter-proxy` located in the `Workflow Restarter TEST`.  For example, the following will trigger a restart if either the `acceptance` or the `unit` jobs preceeding it fail.  A restart of the failing jobs will be attempted 3 times at which point if the failing jobs continue to fail, then the workflow will be marked as failed.  If, however, at any point the `acceptance` and `unit` both pass fine then the restarted workflow will be marked as successful
