Hi, Alexey

In fact alembic has autogenerate option, so if you created the model you
can use something like "neutron-db-manage --config-file
/etc/neutron/neutron.conf --config-file
/etc/neutron/plugins/ml2/ml2_conf.ini revision --autogenerate" and alembic
will create missing script itself. If you have some problems or questions
about it, you can ask me directly via IRC (akamyshnikova) or an email.
