Add "pull --localcache-repo"
This is a lot like `git clone --reference`, but we chose "localcache" as the
term "reference" is already used.
The main use case I'm targeting this for is the Fedora Atomic Host installer
case where we embed the repo content in the installer, but we may want to
kickstart and download newer content. There, while we want to get a newer ref,
we can still use the local repo as an object cache, since we have it sitting
there in memory anyways.
Another case is where one has a host ostree (say e.g. Fedora Atomic
Workstation), and one wants to create a local archive mirror of FAH. Then one
can use `pull --reference /ostree/repo` and pull the common objects (e.g.
contents of `bash.rpm` etc.)
