Ivar Lazzaro 3c95d18311 Embrane Neutron Plugin
Implements blueprint embrane-neutron-plugin

This commit implements the main Embrane plugin, which covers
route and extratoute extensions.

The plugin will rely on existing plugins for leveraging L2 networks,
for now it only supports OpenVSwitch and vlan networks, but more
supports are to come if the model is approved (or a different one
is suggested).
