Make pagure adaptable for pkgs.fedoraproject.org

pkgs.fedoraproject.org is a place which hosts about 17k git repos for rpms. Presently, it uses cgit. But, we do have Pagure for hosting git repos. After addition of few more features, we will be able to host pkgs.fedoraproject.org on a pagure instance. It will make pagure even more flexible software for hosting git repos and sharing code. I am sure project maintainers of pkgs.fedoraproject.org will like the change.
