Public bug reported:

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.
