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).
