esp8266 AT指令 MQTT连接问题

AT device 软件包是对 AT 组件库和 AT socket 功能的移植，需开启 AT 组件库和 AT socket 功能来获取 AT device 软件包。

先要开启 AT 组件库和 AT socket 功能， 具体路径如下所示：

RT-Thread Components  --->
    Network stack  --->
         Socket abstraction layer  --->
            protocol family type  --->
              [ ] Support lwIP stack
              (*) Support AT Commands stack
开启 AT socket 功能之后，默认开启 AT device 软件包， 具体路径如下所示：

RT-Thread online packages  --->
     IoT - internet of things  --->
        -*- AT DEVICE: RT-Thread AT component porting or samples for different device             
              AT socket device modules (Not selected, please select)  --->    
              Version (latest)  --->
AT socket device modules: AT 设备选择，目前支持 ESP8266、M26/MC20 等设备；
Version: 下载软件包版本；
