Ok, at the risk of answering my own question, there's a third option, which
is to output an event for all stack transitions, not only resource
transitions. This appears to be the way the CFN event API works AFAICS.
I guess the event would have a dummy OS::Heat::Stack type and then you
could find the most recent transition to e.g UPDATE_IN_PROGRESS in the
events and use that as a marker so you only list results after that event?
