1. After deployment - don't update nailgun DB - no HW changes accepted.
2. Before deployment - warn user that networks from removed NICs are moved or deleted. User should be able to reallocate such networks (via UI preferably). AFAIS, there are several options here:
a. move all networks to other NIC(s)
b. move them but keep available for allocation
c. delete them but allow to add again
