    Stop upgrade if a task on one node fails

    When we were upgrading multiple nodes at the same time,
    e.g. controllers, and a taks on one of the nodes failed, the other
    nodes would keep upgrading. This is undersirable and can be fixed by
    adding any_errors_fatal to the Ansible plays.
