The core method to handle rpc requests. The advantages of using future instead of callback:

1. separate the caller from actual executor, which make it able to handle the future results by the caller's wish 2. simplify the later execution method

CompletableFuture is an excellent choice, whenCompleteAsync will handle the response asynchronously. With an independent thread-pool, it will improve performance and reduce blocking points.
