This class combines the handler we are supposed to call after the request is completed and the original request object. The reason to hold on to the original request is that we have to provide it to the async handler on successful completion. Storing the request object here means we don't have to store it in the classes that do actual work. Those classes tend to forget about the request objects as soon as the required data was extracted from them.
class QueueBufferCallback<RequestType extends AmazonWebServiceRequest, ResultType> {
