git: new class and method for remote repositories

Add a new GitRemote class for representing git remote repositories.
The initial, very limited, version only contains information about the
fetch and push URLs of the remote repository.

Also, add a new GitRepository.get_remotes() method for getting remote
repositories as instances of the new GitRemote class.
