neutron-api needs to load config files when deployed under WSGI process. This patch will do this. neutron-rpc-server also need to be aware of plugin extension. uWSGI seems not happy with eventlet.GreenPool. So this patch will switch to futurist.ThreadPoolExcutor for ML2 OVO push notification. Partially-implements: blueprint run-in-wsgi-server Change-Id: Ia2659c9c8f1deeceefc1c75f1149a1e47c91e7a9 Closes-Bug: #1708389
