Add a new API resource specific to the NSX plugin for registering tenant-owned NSX gateway devices with the NSX controller. This API also allows tenants for managing gateway devices on the NSX backend. The behaviour of the net-gateway extension is mostly unchanged with the only difference that newly created network gateways can now only refer exlusively gateway devices registered using the API resource introduced with this patch. Implements blueprint nsx-remote-net-gw-integration Change-Id: Ia2bdd0164498fe46a027b1d8f5a9d9f4e37558a4
