Title: Fix admin interface selection [PRD-1748]

* add ip address and netmask fields for NodeNICInterface model
* determine admin interface by ip on interface. Iterate over interfaces and if interface has ip which includes to admin subnet it means that it is admin interface
* use object instead of ids in network manager for reducing sql requests (we used ids because we had some misunderstanding how work with sqlalchemy)
