provenance: consider running the origin->revision provenance algorithm on only "releases"
To allow for a more compact provenance index, we should try running the provenance algorithm on the subset of revisions that match a release.
This would be:
- release objects (eventually pointing at a directory)
- revisions in a snapshot matching a known "tag" identifier (refs/tags/*)
