Blueprint nvp-distributed-router This patch adds support for NVP distributed logical routers adding a simple attribute extension. The default router type can be controlled used the default_router_type option in the nvp section of neutron configuration. In order to ensure backward compatibility, pre-existing routers will be treated as centralized routers. Change-Id: Iaab9ffb6071c93990be711ebb56c212230544a7a
