Comment 1 for bug 1806632

Not sure if accurate as we haven't had a TIMEOUT in over a day http://zuul.openstack.org/builds?pipeline=gate&result=post_failure&result=timed_out&result=failure&job_name=tripleo-ci-centos-7-containers-multinode

I'm wondering if this was related to all the scenario jobs we had on stable branches in the gate causing extra transit load.
