Bugs around creating content units
There are some weird things you can do when creating python packages. A couple examples:
1. I can create a content unit with multiple artifacts
2. Relative path for the artifact might not match filename. This can be problematic when serving content as I can create a package X with a relative path Y that's the same as package Y. There's no validation around relative path uniqueness in a repo version.
See https://pulp.plan.io/issues/3428 for how we solved this in pulp_file. Also, I think we may want to create a solution in pulpcore.
