   单注册中心没有问题，原因多注册中心时，getProtocolServiceKey()方法返回的是带/gray的服务名

   这个服务名是通过上下文获得

   在执行org.apache.dubbo.rpc.proxy.InvocationUtil.invoke(invoker, 
rpcInvocation)方法时将放入上下文的

invoker是在ReferenceConfig产生代理时传入的，在ReferenceConfig.createInvokerForRemote()时创建的

   多注册中心情况下产生的invoker url是会带上registry的group属性，导致元数据匹配不上，这样是存在问题的吧？
