Comment 5 for bug 1654203

The only reason I can think of how we ended up with the wrong neutron server configuration is a stale snapshot (before https://review.openstack.org/#/c/390847/ was merged) that was used for the nodes.
Otherwise there should have been proper extension_drivers setting with "dns" value in list.

Fuel (QA?) team, any comments on the matter will be of great help :)
