Public bug reported:

Context and information:
--------------------------------------
Currently, 404 is seen by the user when "image-delete" call is made via the Glance API or through the Images API of Nova for an Image in "deleted" status.

However, if an Image is in "pending_delete" and a user with the UUID of
that Image tries "image-delete" call from the Nova API, she gets a back
a 403 which is not consistent. The user should get a 404 back.

Notes:
----------
* The user needs to specify the UUID, name is not sufficient.
* For "image-show" call the user is able to see the Image in DELETED status with the appropriate metadata for Image in "deleted" or "pending_delete" status in Glance as nova passes-in the force_show_deleted=True flag by default.

Feedback needed and action to be taken:
---------------------------------------------------------------
Nova should be able to return a 404 back to the user while issuing a "image-delete" call if the Image is flagged deleted in the Glance DB (deleted=True), irrespective of the Image status in "deleted" or "pending_delete".
