Added auro for listing

These are the same instance IDs from our OpenStack docs. I just want to confirm, you've tested this end-to-end and everything works properly?

If you're importing our standard OpenStack images, you must be running the metadata service and explicitly turn off config-drive for the variable substitution to work. Can you verify that it does? The easiest way is to boot three machines and make sure `fleet list-machines` shows all three.
