thrift 生成代码后，types 和 handler 的 package name 是一致的，thrift client 的 package name 也很相似
例如 thrift namespace 是 a.b.c_service 里面有一个 CService，types package name 是 c_service，thrift client package name 是 cservice、handler 的 package name 要求和 thrift namespace 一致是 c_service。
看代码和引用的时候都比较混乱
Describe the solution you'd like
package name 支持各自自定义
