cluster-wait-for-members
Creates a critical alert if a bootstrap Task failure occurs.
This task makes the cluster pipeline wait until all the cluster members have completed their workflows. It does this by waiting on individual machines to create the WorkflowComplete = true state. This means that the loop is waiting events, not polling the API.
Since there is no "break" in the loop, you cannot stop this loop from the cluster pipeline; however, you can easily break the loop by clearing the cluster machines Workflow and marking them Ready.
