[Feature]: 集成nrm的功能？

[kinfuy]

What problem does this feature solve

当前nrm的最新版本nrm@1.2.5 不显示当前源地址Pana/nrm#111 过了一年也没有修复。

What does the proposed API look like

需要考虑当前命令区分，冲突问题,初期只考虑迁移常用的命令
- 方案1：子命令集
- gacm nrm add
- gacm nrm use xxx
- gacm nrm alias xxx xxx
- gacm nrm delete xxx
- gacm nrm ls

• 方案2： gnrm 命令
  - gnrm use xxx
  - gnrm add xxx
  - gnrm alias xxx
  - gnrm ls xxx
  - gnrm use xxx
  -
