功能介绍：
1、调用阿里云API，收集所有区域 ECS 信息
2、将需要的数据整理、生成 Excel 文档
3、关于阿里 sdk 的安装，api 的调用请参考阿里云官网
4、xlsxwriter 请参考这里：http://xlsxwriter.readthedocs.org/

    1、获取该区域全部主机详细信息
    2、参数：cn-qingdao、cn-hangzhou、cn-beijing 等

    # 与阿里云建立有效连接
    clt = client.AcsClient(key, secret, zone)

    request.set_accept_format(‘json‘)
    # 发起请求，获取数据
    result = json.loads(clt.do_action(request)).get(‘Instances‘).get(‘Instance‘)

    ‘‘‘
    从全部数据中整理出需要的数据

    1、设置 Excel 样式
    2、将数据写入到 Excel 中
