Aggregates are host-based. So, if you want to know the list of instances
running on specific aggregates, you first need to get the list of hosts
being in those aggregates and then you loop over each host for knowing
the instance list per host.
AFAIK, there is no helper method on the object side that does that
directly neither in the DB API, so that's a Python consumption.
