standard config injection

         `main` 
        |        \
first   |         \import
reads   |          \other 
outer   |           \modules/pkgs
config  |            \
and     |           other modules/pkgs
inject  |               \
        |                \
        |                 \ (now global config and infrastructure are ready)
        |                  \
        v                   v
  a module/pkg that provides global config and infrastructure

主程序main启动时从外部读取配置，然后注入到a module/pkg that provides global config and infrastructure
这样主程序在进入业务逻辑之前就完成了 全局配置 和 依赖的基础设施 的初始化
其他modules/pkgs直接使用global config and infrastructure即可
