Title:
  Improve performance of _get_dvr_sync_data

Status in neutron:
  Fix Released

Bug description:
  Today, when scheduling a router to a host, _get_dvr_sync_data makes a
  call to get all ports on that host.   This causes the time to schedule
  a new router to increase as the number of routers on the host
  increases.

  What can we do to improve performance by limiting the number of ports
  that we need to return to the agent?

  Marked high and kilo-backport-potential because the source problem is
  in an existing operator cloud running stable/kilo
