Title:
  Duplicated messages in agent's fanout topic

Status in OpenStack Neutron (virtual network service):
  Fix Released
Status in neutron juno series:
  Fix Committed

Bug description:
  Steps to reproduce on devstack:
  1. Create the router:
       neutron router-create test
  2. Set gateway for the router:
       neutron router-gateway-set test public
  3. Delete the router:
       neutron router-delete test

  The notification about router deletion arrives into L3 agent twice:
  2015-01-21 10:53:48.401 DEBUG neutron.agent.l3.agent [req-ce68777f-da33-4381-a7ff-9b8c0eaac380 demo bdb38765a9394f2c962b952675f65073] Got router deleted notification for 10bf431d-6c76-4b87-8db1-57e7fb69076

  Notifications are processed sequentially, the first successfully removes the router, while the second results in warning:
  2015-01-21 10:53:50.957 WARNING neutron.agent.l3.agent [req-ce68777f-da33-4381-a7ff-9b8c0eaac380 demo bdb38765a9394f2c962b952675f65073] Info for router 10bf431d-6c76-4b87-8db1-57e7fb690768 were not found. Skipping router removal
