So we need to modify the caller to call `CreateRepository` with the correct `ObjectHash`. I'm unclear what is actually calling `CreateRepository` though. Is it workhorse/gitlab-shell or is it rails? We would need to inspect the pack-protocol data coming from the client to see what `object-format=<sha1|sha256>` is, and set the `ObjectHash` field properly.
