[openstack-dev] [Neutron][TripleO] Neutron DB migrations best practice

So we had this bug earlier in the week;
https://bugs.launchpad.net/tripleo/+bug/1283921

   Table 'ovs_neutron.ml2_vlan_allocations' doesn't exist" in neutron-server.log

We fixed this by running neutron-db-migrate upgrade head... which we
figured out by googling and asking weird questions in
#openstack-neutron.

But what are we meant to do? Nova etc are dead easy: nova-manage db
sync every time the code changes, done.

Neutron seems to do something special and different here, and it's not
documented from an ops perspective AFAICT - so - please help, cluebats
needed!
