Public bug reported:

We refresh public glance images in our public cloud every month, and we
set the old images to private.

When you do:

openstack server show uuid

of course the instance knows the uuid of the glance image that was
originally used to create the instance.

We noticed that Horizon, to write on the web interface the description
of the image used to start the instance, makes a lot of requests for
public images that are not public anymore.

This is okay, but the 404 is not logged as a WARNING, but as an ERROR
with a long stack trace.

This is 18 lines for each 404 and is poisoning our log files:
