Subject: www: support cloning individual v2 git partitions

This will require multiple client invocations, but should reduce
load on the server and make it easier for readers to only clone
the latest data.

Unfortunately, supporting a cloneurl file for externally-hosted
repos will be more difficult as we cannot easily know if the
clones use v1 or v2 repositories, or how many git partitions
they have.
