Determine which outputs need to be stored, where, and how

[not-the-fish]

pgdedupe output is not documented, so we will need to do that (dssg/pgdedupe#64) to determine which outputs are critical for reproducibility, ingesting updated data (#14), and model evaluation.

See also dssg/pgdedupe#66 for cleanup step in pgdedupe. Tables that need to be kept will need to be prefixed/postfixed with model hash before cleanup to be cached.
