给fastjson增加个扩展把

5

- [x] I have searched the [issues](https://github.com/apache/dubbo/issues) of this repository and believe that this is not a duplicate. ## Describe the proposal 给fastjson增加个扩展吧，fastjson1之前很多版本出现了安全漏洞，我们也一直建议去fastjson1 但是Dubbo强依赖了这个，无法处理，建议将json库放到扩展里面，默认可以是fastjson，后续我们提供gson jackson或者fastjson2都会方便一些

当服务重启后ServiceInstancesChangedListener一直在重试

 我觉得应该在两个角度去考虑 1. 在Dubbo2中我们应该根据`接口+服务分组+版本号`来去重 2. 但是在Dubbo3中我们支持了多实例，`接口+服务分组+版本号`不再是唯一条件，在Dubbo3中Framework、Application也应该是去重条件 但是现在URL#equals方法中，只有URLAddress（既`ip+port`）和URLParam
