增加自定义TCP协议设备监控

[boyucjz]

实现方案：
1.配置设备IP及端口号
2.配置请求消息
3.配置回复消息解析规则（起始字节、结束字节、数据类型）

Maybe we can expand on port telnet monitor？

[boyucjz]

建议从这几个框架里选择 Java NIO 、Netty（MessageToByteEncoder、ByteToMessageDecoder）

It looks like a Tcp heartbeat detection mechanism. Do we need to implement it? @tomsun28

[tomsun28]

hi if need detect tcp available, the current telent monitoring can support this.

找到了一个可参考实例方案
thingsboard_gateway 的 socket 连接器

[tomsun28]

hi, can you describe the way how to custom if have time, and it is possible implement in HertzBeat ?

[boyucjz]

I'll organize it these days

[boyucjz]

1.引用hutool-socket第三方java库进行socket开发
2.配置服务器名称、服务器IP、端口号
3.配置连接超时时间
4.数据缓冲区配置：发送缓冲区大小、接收缓冲区大小
5.配置采集命令（16进制串）
6.配置解析规则
6.1返回字节流顺序：高序字节\低序字节
6.2要素名称、要素起始字节、要素字节长度、要素类型（short int long float double char）
