   @ashb: Maybe I even have a much better idea. Versioned graphs. Meaning, storing the graph only if it was been changed comparing to the last run.
   - Add graph id/version to DagRun
   - Change execution_date -> graph_id in DagEdge
   
   This is not such a hard change. The good thing here is that be can detect graph changes even. Less data is stored in the database.
