Comment 2 for bug 1735667

This is not an issue for new style jobs that use the ansible role: https://github.com/openstack/tempest/blob/master/roles/process-stackviz/tasks/main.yaml#L12, since it uses subunit directly, and the role that produces subunit accounts for both testr and stestr: https://github.com/openstack-infra/zuul-jobs/blob/master/roles/process-test-results/tasks/main.yaml
