    Clear DVR MAC on last agent deletion from host
    
    Once all agents are deleted from a host, the DVR MAC generated
    for that host should be deleted as well to prevent a buildup of
    pointless flows generated in the OVS agent for hosts that don't
    exist.

Title:
  host dvr macs remain after agents deleted

Status in neutron:
  Fix Released

Bug description:
  The DVR macs and the subsequent rules for them stay around
  indefinitely even after all agents related to that host are removed
  from the database.

  So a system with lots of host churn (e.g. container based deployment),
  will end up with flow tables that look like this on the active agents:
