单测: 使用兼容性更好的xgo替换gomonkey

[xhd2015]

在这个PR中，我使用xgo替换了gomonkey。 xgo相对于gomonkey具有如下优点:

• 不依赖asm, 纯go实现，兼容所有的OS和架构
• 并发安全，多组用例同时mock，不会相互影响
• API更加简单，不需要defer patch.Reset()等代码

xgo的项目地址: https://github.com/xhd2015/xgo

使用xgo进行单测的步骤:

1. 安装

   
   # macOS and Linux (and WSL)
   curl -fsSL https://github.com/xhd2015/xgo/raw/master/install.sh | bash

windows

powershell -c "irm github.com/xhd2015/xgo/raw/master/install.ps1|iex"

2. 执行test
```sh
xgo test ./...

测试结果:

 xgo test ./...
xgo is taking a while to setup, please wait...
