Title: Adding/Removing instances from targetpool requires a list.

This fixes a bug with attaching/detaching nodes from loadbalancers.
(Attach/Detach wasn't working)

This may have changed in the API at some point after I wrote the initial load balancing implementation, but I'm not sure when. If so, I missed the change previously.
