Add the ability to specify a git remote

Rather than fill the git provider with hard-coded references to
origin, it would be better to abstract out which remote the resource
is fetching from.  But since this is only relevant to decentralized
version-control systems, a multiple_remotes feature was added for
the parameter to depend on.  So far this is only implemented for git
remotes, but it could be implemented for other VCSs as well.
