Review comment:
```suggestion
@provide_session
@cli_utils.action_logging
def dag_reserialize(args, session=None):
session.query(SerializedDagModel).delete(synchronize_session=False)
```
Skip synchronisation to make the operation slightly faster. The session is
going to end immediately after this so there’s no point to keep things in sync.
The `provide_session` decorator calls `commit()` automatically, we don’t
need to do that again.
