Requesting permission to kick off AirFlow jobs for @Tchanders, specifically for running backfills on PSI's metrics: https://superset.wikimedia.org/superset/dashboard/788/

We are tracking a few topline metrics for the first time. As we have learnt more about these metrics, their definitions have already changed a few times, and they are likely to change again in the future. Each time they change we will need to run backfills, and it would be quicker if we could kick these off ourselves.
