Comment 17 for bug 1717545

@Arx, right but that job does not test tripleo (see http://logs.openstack.org/69/501669/4/gate/gate-puppet-openstack-integration-4-scenario001-tempest-ubuntu-xenial/244fbb2/logs/etc/nova/nova.conf.txt.gz and the missing extra parameters in the connection strings), so it is not relevant to this discussion.
