This patch introduces API and DB plugin for flavor framework. API adds Flavors and Service Profiles which are resources available only for admins to operate. This framework then should be leveraged by advanced services. Included tempest API tests in neutron tree Implements: blueprint neutron-flavor-framework Change-Id: I99ba0ce520ae3d8696eca5c994777c7d5ba3d4b1 Co-Authored-By: Doug Wiegley <dougw@a10networks.com> Co-Authored-By: Madhusudhan Kandadai <madhusudhan.kandadai@hp.com>
