Comment 1 for bug 1537833

I see two ways to solve a problem.
First one is to use --insecure option in openstack clients when accessing MOS here [0] and at another places.

Second way is to make changes in testing infra, to allow resolve CN name via hosts file. So, it will be possible to set some name at CN filed, and than after cluster creation get public vip IP, add matching line to the hosts file.
