* A handler for the {@link com.hazelcast.spi.OperationService} when it has calculated a response. This way you can hook
* into the Operation execution and decide what to do with it: for example, send it to the right machine.
*
* The difference between the {@link ResponseHandler} and the OperationResponseHandler is that the OperationResponseHandler
* can be re-used since it isn't tied to a particular execution.
*
* Also during the development of Hazelcast 3.6 additional methods will be added to the OperationResponseHandler for certain
* types of responses like exceptions, backup complete etc.
