git-repo is a git client tool that supports project management systems that include git projects, such as GitHub , GitLab, BitBucket, etc.
It has a simpler and consistent interface for working with them all, such as git-repo <target> request create to submit a patch for review, and git-repo <target> request fetch <id> to fetch a patch for review.
It does not yet understand git projects on Phabricator.
This task is to create a basic git-repo backend which can clone a repository hosted on Phabricator.
