[Users] vlan on mgmt network

[Moti Asayag]

There is an open bug in regards to configuring the management
network on top of a vlan:

https://bugzilla.redhat.com/show_bug.cgi?id=906359

The system stability might get worse due to the new feature
"multi host network configuration" which applies logical network
changes to the entire DC's hosts.
