    Fix device_owner during DVR and HA migrations
    
    When HA router is migrated to DVR, router's
    DEVICE_OWNER_HA_REPLICATED_INT interface has to be updated
    to DEVICE_OWNER_DVR_INTERFACE.
    
    Similarly for DVR to HA migration, DEVICE_OWNER_DVR_INTERFACE
    has to be updated to DEVICE_OWNER_HA_REPLICATED_INT.
    
    Also, for Legacy to HA migration, DEVICE_OWNER_ROUTER_INTF
    has to be updated to DEVICE_OWNER_HA_REPLICATED_INT.
    
    Also added unit test cases for all possible migration cases.

Title:
  Router interface not updated during DVR->HA, HA->DVR migratons

Status in neutron:
  Fix Released

Bug description:
  While debugging migration tests failures for gate-tempest-dsvm-
  neutron-dvr-multinode-scenario-ubuntu-xenial-nv job, I observed that
  device_owner is not updated properly during migration.

  When HA router is migrated to DVR(i.e HA->DVR), router's
  DEVICE_OWNER_HA_REPLICATED_INT interface has to be updated to
  DEVICE_OWNER_DVR_INTERFACE. Similarly for DVR to HA migration,
  DEVICE_OWNER_DVR_INTERFACE has to be replaced with
  DEVICE_OWNER_HA_REPLICATED_INT.

  But the existing migration code [1] doesn't consider
  DEVICE_OWNER_HA_REPLICATED_INT. As DVR and HA code depends on these
  device_owner types, it has to be updated properly.
