tjenness pointed out during the review of
DM-22655 that we have gen2 repos to test obs_lsst gen2-3 conversion. We will also need to specify some configs specific to this package. Implementing `test_convert2to3.py` would be an easy start, once the right test data is identified.
tjenness: In your comment you said "This repo even comes with a bunch of gen2 repos...": where are they, and what to they contain? We do have `testdata_lsst`, but that's not in lsst_distrib (how big is it? The readme isn't helpful.) and it doesn't contain premade gen2 repos.
