No doubt the bus should be (and is) dumb plumbing.  What we are talking 
about are the apps using the bus, and what makes it easy for them to 
provide and consume messages.  It seems like we could do a little better 
than reading docs, screwing up, and retrying, at least for Java 
clients.  I would happily incorporate a Gson-ready pojo guaranteed to 
parse out the Json dropped on HawkularMetricsData topic.  I don't really 
care which client jar I need to get it, whether it was a kettle client 
jar or a metrics client jar.
