Wrong network information is shown on UI (nova-network)

[Mike Scherbakov]

No matter HA / Simple mode, choose Nova-network, VLAN mode. Make correct configuration, and then try to open node network interfaces screen. There will wrong info about VLANs on logical networks, and incorrect warning. Can be easily reproduced on fake UI:
1) go thru wizard, all defaults
2) choose nova-network VLAN mode, Save
3) add first node to env, open network interfaces configuration for that node. You will see attached screenshot.

When you deploy (changed only vlan for storage, set to 500, before hitting deploy button), the following message is sent to Astute:

[Mike Scherbakov (mihgen)]

Could be caused by the following response from Nailgun:
http://paste.openstack.org/show/75735/
which happens when I open node network interfaces screen, /api/clusters/1/network_configuration
