powershell脚本创建3scale api

使用powershell来创建3scale api，

3scale提供了管理api，rest服务，通过这些api可以操作3scale，代替界面鼠标点点

powershell里使用Invoke-WebRequest这个函数来调用rest服务，

有个注意点是要忽略https自签证书验证

还有个注意点是设置出错的时候停止运行，因为默认有错误还是会继续往下执行

总共2个文件，一个是ps文件，一个是csv文件

ps文件如下，api name是hard code在里面xtest1，

csv文件里有3个字段，一个是http 方法 get post等，另外一个计量名字，api resource的缩写，统计用，还有一个是resource

好处是使用windows原生工具，不用安装其他任何工具，比如curl，go，java，python等。

局限就是仅限windows，当然现在也可以在linux装powershell，但是估计没多少人会那么干。

扯了那么多废话，上代码。
