jfwood b64228a945 Revive Alembic-based database migration logic.
Alembic migrations were introduced to Barbican a while ago but have not been
used recently. This CR revisits the migration logic and ensures that time-zero
database tables creation is distinguished from Alembic-base schema updates.
The associated database migration script is also revived, allowing for
schema migrations outside of the Barbican boot process.
