Dubbo(5)优化：接口抽取以及依赖版本统一

优化点：

1.在上面provider和consumer程序中都存在DemoProviderService接口了，两个项目中存在同样的东西，代码多余以及不方便管理；

正式的项目中存在很多的接口的，将统一的公共的抽取出来；

2.provider和consumer中存在很多相同的依赖；利用maven的继承统一的管理依赖和版本；

抽取公共的依赖；

 

 

1、项目结构变为了；

 

2.将公共的interface DemoProviderService放到dubbo-api项目里面了，consumer和provider项目都引用这个jar；
