euca-describe-image-attribute -l fails w/ UnknownError:

[Dan Prince]

Using nova 961 w/ Glance.

If I run the following command I get a stack trace in nova-api.log:

euca-describe-image-attribute -l ami-0000000

Looks like we still have a couple discrepancies in how is_pubic is used from the image service.

The attached patch resolves the issue.
