    [AIRFLOW-3973] Commit after each alembic migration (#4797)
    
    If `Variable`s are used in DAGs, and Postgres is used for the internal
    database, a fresh `$ airflow initdb` (or `$ airflow resetdb`) spams the
    logs with error messages (but does not fail).
    
    This commit corrects this by running each migration in a separate
    transaction.
