Stephen Finucane 1ba2c1c55d db: Enable auto-generation of migrations
Let's take advantage of the features that alembic provides [1]. We use
this opportunity to clean up how we do our base model creation and
remove the downgrade section from the migration script template, since
we don't support downgrades.
