Support asynchronous Servlet in Sentinel Web Servlet Filter.
Spring Boot中使用 CompletableFuture<T> or DefferdResult<T> or Callable<T> 作为返回值，引入 Sentinel CommonFilter 后无法响应，且无法正确统计。是否支持两种形式（同步与异步 Servlet）并存，比如使用案例如下：
@RestController
public class AsyncController {
@GetMapping("/async")
public CompletableFuture<String> async() {
return CompletableFuture.supplyAsync(() -> {
try {
TimeUnit.SECONDS.sleep(1);
} catch (InterruptedException e) {
e.printStackTrace();
}
return "async\";
}
);
}
}
