选举Leader的一个需求是 candidate 请求投票时，如果有超过半数的响应为 success，就获选leader。

但这处代码的实现是：通过 CountDownLatch(size)阻塞实现，且是在全部都响应了才开始判断。

而且这部分的异步任务处理分提交和检测完成两次，觉得写的有点繁琐。个人觉得可使用一个ExecutorCompletionService，写起来更清晰，同时在每次take后检测是否有超过半数的成功响应。

CountDownLatch latch_1 = new CountDownLatch(futureArrayList.size() / 2);
把全部改为一半怎么样？
