Comment 13 for bug 1889729

This bug for glance-simplestreams-sync is still valid. If the glance charm has been configured with image-conversion=true and we use image_import instead of upload, the image will get converted to raw. It looks like Yoshi's fix here is valid, though seems it needs to be rebased: https://review.opendev.org/c/openstack/charm-glance-simplestreams-sync/+/809392
