> isAlive checks are currently completely broken, since the ZK registry does not update
existing ServiceIsntances. Instead it creates new instances each time.
> This causes non-existant nodes to be used for scheduling in case of node failures.
> Also, act on the notifications sent by the registry about nodes going down, or new nodes
being added. (new nodes already handled)
