radicle: namespace peers
The previous iteration of the storage layout for projects organised
peer's subtrees by the `refs/remotes` category. This layout leads to
problems when linking a working copy to the storage project. The fetch
refspec would look something like:

  fetch = +refs/remotes/abc/heads/*:refs/remotes/rad/*

This works perfectly fine when running:

  git fetch rad

but will fail when one tries to specify:

  git fetch rad main

Instead, the command would need to be:

  git fetch remotes/abc/heads/main

This patch proposes to move the use of `refs/namespaces` for each
peer. The layout looks similar in that each peer has a subtree, but
instead it is under `refs/namespaces/<peer>/refs/...`.

The previous refspec would look more familiar in its new form:

  fetch = +refs/heads/*:refs/remotes/rad/*

With this in place running:

  git --namespace=abc rad main

Will work as expected and place the reference under
`refs/remotes/rad/main`. Similary, `git --namespace=abc push` will
work as expected.

Another benefit of this approach is that the use of namespacing means
that a tag is pushed it will be placed under the respective namespace
rather than in the global `refs/tags` category.

The actual implementation needed to work around the fact that
`git2`/`libgit2` does not have any options for fetching or pushing
using namespaces. The working copy code uses processes to shell out to
`git` for namespacing needs.
