This does two things: 1. It makes us check that the QCOW backing_file is unset on those types of images. Nova and Cinder do this already to prevent an arbitrary (and trivial to accomplish) host file exposure exploit. 2. It makes us restrict VMDK files to only allowed subtypes. These files can name arbitrary files on disk as extents, providing the same sort of attack. Default that list to just the types we believe are actually useful for openstack, and which are monolithic. The configuration option to specify allowed subtypes is added in glance's config and not in the import options so that we can extend this check later to image ingest. The format_inspector can tell us what the type and subtype is, and we could reject those images early and even in the case where image_conversion is not enabled.
