[glance] Listing all images with a set of custom properties

I am looking for a way to programmatically get all images that have been associated with a set of custom properties. Ideally, I should be able to say 'give me all images that have key1=value1, key2=value2, etc. Failing that, at least get all images that have the named keys key1, key2, etc. irrespective of their values, so I can filter for the values myself. I was looking at [1], specifically [2], and came up short. Any recommendations?
