In the Previous BP [1], support for iscsi backend is introduced into glance. However, it was abandoned because of Cinder backend replacement.
The reason is that all storage backend details should be hidden by cinder, not exposed to other projects. However, with more and more interest in "Converged Storage" like Ceph, it's necessary to expose storage backend to glance as well as cinder. An example is that when transferring bits between volume and image, we can utilize advanced storage offload capability like linked clone to do very fast instant copy. Maybe we need a more general glance backend location support not only with iscsi.
