- use Alembic to migrate the PostgreSQL database + create initial migration script to set up the database, as an alternative to db.Base.metadata.create_all() + integrate Alembic into the test suite; the db_engine fixture now has two modes: * create the latest version of tables all at once * invoke `alembic upgrade head` => the "e2e" tests are all run twice, once in each mode; this ensures that the migration scripts re-create the same database schema as db.Base.metadata.create_all() would * in both modes, a temporary PostgreSQL schema is used to create the tables in => could now run "e2e" tests against production database and still have isolation - make the configuration module public (to be used by Alembic) - adjust linting rules for Alembic
