Nguyen Phuong An 2f98f56cb5 Allow neutron-api load config from WSGI process
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
