> Right now each role can define event handlers for bootstrap and configure. I
> suggest that the Whirr core should be aware of more service lifecycle events
> like: start, stop & cleanup. This semantic improvement should allow us to add
> more features like: cluster reconfiguration (e.g. update Hadoop settings and
> restart all the nodes - rolling restart), add / remove nodes etc.
