Title:
  Failed import of one store will remain in progress forever if
  all_stores_must_succeed=True

Status in Glance:
  Fix Released
Status in Glance ussuri series:
  New

Bug description:
  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
