   referenceCount 应该和 DubboInvoker 实例的数量相等，只是你看看ServiceDiscoveryRegistryDirectory的urlInvokerMap结构，你就明白了。
   这个map是当client收到注册中心notify时对URL相关的invoker进行更新的，key是URL，value是这个URL对应的其中一个invoker，但是这个URL对应的invoker并不都是由ServiceDiscoveryRegistryDirectory创建的，当初我曾尝试过把这个map的value搞成set集合，但是发现要伤筋动骨大改，涉及的内容太多了，就退回来搞了个destryAll。
