    Cleanup fanout queues on ovs agent stop

    Previously when a neutron-openvswitch-agent was stopped it left
    behind the following fanout queues in rabbitmq:
    neutron-vo-Network-1.0_fanout_someuuid
    neutron-vo-Port-1.1_fanout_someuuid
    neutron-vo-SecurityGroup-1.0_fanout_someuuid
    neutron-vo-SecurityGroupRule-1.0_fanout_someuuid
    neutron-vo-SubPort-1.0_fanout_someuuid
    neutron-vo-Subnet-1.0_fanout_someuuid
    neutron-vo-Trunk-1.1_fanout_someuuid

    In this change we ensure that all but the SubPort and Trunk fanout
    queues are correctly removed from rabbitmq by cleanly stopping the
    RemoteResourceCache when the agent stops.
