数据流转：

1.mqtt数据流转（北向服务端）
script:
this.translate=function(msg,device){
return
  {
    "topic":"topic",//推送topic
    "payload":JSON.stringify(msg.data)  // 数据，为字符串
  }
}
2.kafka数据流转（北向服务端
script:
this.translate=function(msg,device){
return
  {
    "topic":"topic",//推送topic
    "payload":JSON.stringify(msg.data),  // 数据，为字符串
  	"partition": 1 // 分区，不需要指定分区就不要传分区kv
  }
}
