My concern is that correct behavior would be not to write to non
existent topic. Looks like some code currently common to both backend
drivers should be moved lower to a specific backend and removed from the
others.

Title:
  Nobody listens to network delete notifications (OVS specific)

Status in neutron:
  New

Bug description:
  Here it can be seen that agents are notified of network delete event:
  https://github.com/openstack/neutron/blob/8.0.0.0b2/neutron/plugins/ml2/rpc.py#L304

  But on the agent side only network update events are being listened:
  https://github.com/openstack/neutron/blob/8.0.0.0b2/neutron/plugins/ml2/drivers/openvswitch/agent/ovs_neutron_agent.py#L374

  That was uncovered during testing of Pika driver, because it does not
  allow to send messages to queues which do not exist, unlike current
  Rabbit (Kombu) driver. That behaviour will probably be changed in Pika
  driver, but still it is worthy to get rid of unnecessary notifications
  on Neutron side.
