Remove rootfs service in place of snapshot service. Adds diff service for extracting and creating diffs. Diff creation is not yet implemented. This service allows pulling or creating images without needing root access to mount. Additionally in the future this will allow containerd to ensure extractions happen safely in a chroot if needed.
