      harbor低版本的数据不能直接导入到高版本，因为其中数据库字段，表等等均会在版本的升级过程中发生变化，需要将老的harbor中的镜像导出到本地，打上tag，再推送到新的harbor服务器，其整体思路如下：

           1.通过harbor的API获取到所有的项目

           2.通过项目获取到所有的repo

           3.通过repo获取到所有的tag

           4.将项目，repo，tag拼接起来，形成一个pull，tag和push的命令列表并依次执行

需要注意点：

         新版本的harbor需要post请求需要带上cookies字段，为了防止csrf攻击
