Assign public network where not needed is possible by group assigment

[Krzysztof Szukiełojć]

Detailed bug description:
Correctly using UI there is possiblity to assign public networks to nodes which should no have this network.
We should add check for assigned networks here: https://github.com/openstack/fuel-web/blob/master/nailgun/nailgun/api/v1/validators/network.py#L834

Expected results:
Public network should not be assigned in group assigments.

Actual result:
Public network assigned everywhere.

After patch for nailgun will be delivered. UI needs to add same logic for interfaces at it uses for disks. Eg Check if all nodes are able to have same networks before group configuration.
