Salvatore Orlando 268d39c230 L3 API support for nicira plugin
blueprint nvp-l3-api

This patch adds supports the Quantum L3 API extension to the nicira NVP
Quantum Plugin.

The patch includes code for managing Quantum routers, router interfaces,
external gateways, and floating IPs, and for applying the relevant
configurations on the NVP controller using the NVP API.

The patch also includes NVP-specific support for access to the nova
metadata server via injection of a host route in VM instances.
