Listens to oslo_messaging for database updates from octavia. When neutron-lbaas is being used with octavia this queing system will be used to so that health check and status updates from octavia are sent to neutron-lbaas so that neutron updates its database in sync with octavia. See CR https://review.openstack.org/218735 for details on the octavia side. This event handler can actually be used for other drivers as long, but for now its only used for octavia.
