Title:
  neutron-openvswitch-agent leak sg iptables rules

Status in neutron:
  Expired

Bug description:
  In function 'treat_devices_added_or_updated', port not exist at 'br-
  int' will be added into 'skipped_devices', and return to parent
  function 'process_network_ports', and 'process_network_ports' will
  remove these ports from port_info['current'].

  If a port updated due to security group changing, and the port deleted
  just in function 'treat_devices_added_or_updated', so the port aded
  into 'skipped_devices', then it removed from port_info['current'].
  When next 'scan_port', the port not in 'registered_ports', so it not
  added into port_info['removed'], it's chains and rules will never been
  removed. These waste chains and rules stay in iptables util ovs-agent
  restart or compute node restart.
