Add support routes using salt.states.network. Testing on ubuntu 14.04

Hello! I read http://docs.saltstack.com/en/latest/ref/states/all/salt.states.network.html and add support routes for you formula, after I add support "system".
Please use defaults.yaml and merge it with pillars:

{% set datamap = salt['grains.filter_by'](rawmap, merge=salt['pillar.get']('network:lookup')) %}
