Title:
  Frozen (external) DB tables not prevented from alteration

Status in neutron:
  Fix Released

Bug description:
  Database models are being split out of neutron.
  The FW/LB/VPNaaS models have already been split.

  Once a model is split out of neutron, it may no longer be altered by
  any neutron alembic migration.

  We need to add a test case to the DB migration tests that checks that
  no external tables are altered after they are split.

  The names of external tables are recorded in neutron/db/migration/alembic_migrations/external.py
  We will need to add the revision when the split occurred for each table or group of tables.
