I guess that error is because I put a "with_items" in there.
How does everyone else do this? I don't understand how to loop
asynchronously. See pseudo-code:
< start all 5 at once: >
< start up openstack host >
< assign it a floating ip >
< capture the floating ip >
< end when all 5 have a floating ip >
< wait for all 5 floating IPs to have an open SSH port >
