This patch shows how to use a neutron-lib released API definition for
the VPNaaS extensions. This is a baby step towards a
consolidated set of Neutron APIs.
See I06760fbbbc87570412a21364fba58efe880a907b for more details.
The method get_namespace in API extensions is also removed during this
migration. Since it was removed from neutron long time ago [1].
