Description of problem: There's a bug in the ovirt_vms ansible module that prevents you from launching VMs on a custom cluster using the default network profile, so we're going to temporarily disable custom datacenter/cluster configuration. This should just be a very temporary fix, just for the 1.1 release. Probably the best thing to do is just make the fields uneditable for now. I believe this is already the case for self-hosted, so you can probably just work off that logic.
