akka.routing.ConsistentHashingRouter
If you don't define the hashMapping when constructing the akka.routing.ConsistentHashingRouter and messages can't implement akka.routing.ConsistentHashingRouter.ConsistentHashable themselves they can we wrapped by this envelope instead. The router will only send the wrapped message to the destination, i.e. the envelope will be stripped off.
