Title:
  FirewallNotFound exceptions when deleting the firewall in FWaaS-DVR

Status in neutron:
  Fix Released

Bug description:
  We have four nodes, and we deploy both the FWaaS and DVR services.
  When deleting the firewall, we always get three FirewallNotFound
  exceptions. At present, we believe that, in DVR environment, evey node
  would run a L3-agent service. This causes a plugin corresponding to
  multiple agents. And each agent will call back the plugin's
  firewall_deleted() (neutron_fwaas/services/firewall/fwaas_plugin.py)
  to delete the instance in DB, but only the first agent will succeed.

  How to reproduce:
  - first create a firewall applied to a DVR router
  - then delete it

  $ neutron router-show test-fwaas
