/*
* Function: mosquitto_connect
*
* 连接MQTT服务器接口
*
* Parameters:
* mosq - 一个初始化的mosquitto对象
* host - 连接的服务器地址或IP地址
* port - 连接端口，默认为1883
* keepalive - 检测当前是否在线的周期秒数。
* 在检测的时候客户端会发送PING命令，待接收到返回信息后更新网络连接状态
* 发送周期起始时间为最后一个发送的信息时间或PING命令时间之后开始算起。
*
* Returns:
* MOSQ_ERR_SUCCESS - 连接成功
* MOSQ_ERR_INVAL - 输入参数异常
* MOSQ_ERR_ERRNO - ???:未知错误类型
*
