    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

Title:
  wsgi and rpc-server has issues with dhcp when creating subnet

Status in neutron:
  Fix Released

Bug description:
  I'm not sure how to trace this down further, but with neutron-api
  running as a wsgi script in a container, and neutron-rpc-server
  running in a separate container. When creating a subnet in the
  openstack-cli, e.g. "subnet create --network network1 --subnet-range
  10.0.0.0/24 subnet1", the rpc-server logs and dhcp-agent logs fill up
  with these errors;

  ValueError: Unrecognized attribute(s) 'binding:host_id'

  I'm attaching some logs with a stack-trace.
