windows auto activate

目前所支持的windows镜像都是未激活状态，未激活状态下很多功能无法使用。

以后将要实现的功能是，windows虚机启动后，网络正常后能与KMS服务器通信，自动激活key

 

 

目前想到两种办法：

1、bat批处理脚本，开启自动运行，利用slmgr激活

2、cloudbase-init的LocalScriptsPlugin功能，将写好的脚本放在 cloudbaseinit.plugins.common.localscripts目录下

3、cloudbaseinit.plugins.windows.licensing.WindowsLicensingPlugin插件，该插件在代码里能实现set kms主机，及slmgr直接注入key

cloud-init配置文件，需要开启cloudbaseinit.plugins.windows.licensing.WindowsLicensingPlugin插件,activate_windows=true，check_latest_version=false
