Public bug reported:

If import is called with all_stores_must_succeed=True and a store fails
during set_image_data(), the store will remain in
os_glance_importing_stores forever, never going into the
os_glance_failed_import list. This means a polling client will never
notice that the import failed. Further, if multiple stores are included
in the import, and the failure happens in the later stores, the revert
process will remove the earlier stores (after they had already been
reported as available in stores). This means a polling client doing an
import on an image already in store1 to store2,store3,store4 will see
the following progression:

stores=store1;os_glance_importing_to_stores=store2,store3,store4

stores=store1,store2;os_glance_importing_to_stores=store3,store4

stores=store1,store2,store3;os_glance_importing_to_stores=store4

stores=store1,store2;os_glance_importing_to_stores=store4

stores=store1;os_glance_importing_to_stores=store4

The last line, forever, and never see anything in
os_glance_failed_import
