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. Change-Id: I20b45190f1eaca0229d30871b25484b90298a18b
