Hi! I guess you hit https://bugs.launchpad.net/neutron/+bug/1503342, seems we need to reopen it.
I can only suggest to create migration manually "neutron-db-manage --config-file /etc/neutron/neutron.conf revision -m "description of revision" --contact/expand. Then you will see path to file which was generated, you can edit this file and add operation that you need.
