-------------------------------------

Is this intended for example programs and test?

> hi, all
> I have written a MockNetCat class, which help developers start a netcat programmatically, instead of manually launching
> {{nc -lk 9999}}
> command for test
> developers can start a mock NetCat server in test cases and send data to the server (simulating user input text in the nc shell)
> is this feature ok to create a PR to flink?
> use of MockNetCat is very simple, like:
> {{var nc: MockNetCat = MockNetCat.start(9999);}}
> this starts a NetCat server, and data can be generated using following code:
> {{nc.writeData("hello\r\nworld\r\nbye\r\nworld\r\n");}}
