    use separate device owner for HA router interface
    
    Currently HA router interface port uses DEVICE_OWNER_ROUTER_INTF as
    device owner(like normal router interface). So to check if a port is
    a HA router interface port, we have to perform a DB operation.
    
    Neutron server at many places may need check if a port is HA router
    interface port and perform different set of operations, then it has
    to access DB for this. Instead of that, if this information is
    available as port's device owner, we can avoid DB access every time.

Title:
  seperate device owner flag for HA router interface port

Status in neutron:
  Fix Released

Bug description:
  Currently HA router interface port uses DEVICE_OWNER_ROUTER_INTF as
  device owner(like normal router interface). So to check if a port is a
  HA router interface port, we have to perform a DB operation.

  
  Neutron server at many places(functions in plugin.py, rpc.py, mech_driver.py [1]) may need check if a port is HA router interface port and perform different set of operations, then it has to access DB for this. Instead if this information is available as port's device owner, we can avoid DB access every time.
