Public bug reported:
Deleting a security group results in each agent of the region running
a bulk_pull query for all the rules in the security group against the
neutron-rpc. This is incurs a load on neutron-rpc, rabbitmq and the db
proportional to the number of agents and the number of security group
rules and has a noticeable impact on larger infrastructures.
How to reproduce:
1. Create a security group.
2. Delete the security group.
3. Observe all the neutron agents are performing a bulk_pull for the deleted
security group.
