detectron2: require coco2017-minimal data (#2022)

Summary:
It seems like detectron2 requires coco2017-minimal data. It gets installed with vision-maskrcnn, but if you want to install requirements only for one model we need the installer scripts for the detectron models to download coco2017-minimal.
