Occasionally a dockless ETL task fails (sometimes due to network/HTTP/server errors, sometimes due to others), leaving temp tables (cf. #68) hanging around.

We should automate the removal of these. I see two strategies:

  1. Upstream a patch to mds-provider that auto-drops them even if the ingest fails. There could be an argument for keeping them around for forsenic reasons, but I likely wouldn't trust them much in practice.
  2. Make a new dag that automates dropping them, running perhaps monthly or weekly.

I'd lean towards option one, though they are not really mutually exclusive.
