Create a bare-bones version of git-prime-clone, which returns the
location of an alternate resource specified by the server that the
client should fetch and build before returning to perform an incremental
fetch.
At this point, no validation is performed of the file's existence, the
file's validity as a fully connected archive, or its correspondence
to the specified resource type in .git/config.
