BVT test failed on getting public vip ip because nailgun provided empty vips data

[Andrey Sledzinskiy]

Steps:
1. Install fuel master
2. Create any cluster
3. Try to get public vip in nailgun

Test failed trying to get public vip ip addr - self.client.get_networks(
                cluster_id)['vips']['public']['ipaddr']

but vips are empty in nailgun - "vips": { }

Basically not assigning IP addresses to VIPs on GET requests was intended. PUTting the network configuration handler or starting a deployment is required now. Is it possible to do that in the test?

[Andrey Sledzinskiy (asledzinskiy)]

We use public vip as value for 'DNS hostname for public TLS endpoints' after cluster creation.
We need to think some workarounds so I suggest revert first and then I'll create a bug to fix it in fuel-qa
