Dell drivers reports NPAR nics as: "em1_1,em1_2,em2_1,em2_2,em3_1,em3_2,em4_1,em4_2,lo"

This is a blocker for discovery, we should get this right in core. We currently parse the interfaces like this:

  VIRTUAL = /\A([a-z0-9]+)_([a-z0-9]+)\Z/
  BRIDGES = /\A(vir)?br(\d+|-[a-z0-9]+)(_nic)?\Z/
  BONDS = /\A(bond\d+)\Z|\A(lagg\d+)\Z/

Foreman thinks that NPARs are virtuals actually. That prevents from detecting correct ipaddress.
