collector实现一个采集器，用于采集指标数据- alicloud_tags_exporter.go 程序主逻辑
- config.json 存储阿里云秘钥信息
- 编译依赖
go get -u github.com/aliyun/alibaba-cloud-sdk-go/sdk
go get github.com/prometheus/client_golang/prometheus/promhttp
go get -u github.com/spf13/viper
执行go build编译运行，然后访问http://localhost:19001/metrics就可以看到采集到的指标数据。
* 使用帮助

-listen-port string
An port to listen on for web interface . (default "19001")
-region string
alicloud region id (default "cn-shanghai")
效果如下：
