Port to Golang

[mjtrangoni]

Hi @marcan,

I wanted to ask you, if you are interested in porting this exporter to Golang.
Why? I have some appliances(I can not install extra system's software there), that runs on old OSs, and does not provide python3.
As Golang give you one static binary, I could use this exporter there. There is many more advantages too, like the tooling, library upgrades, testing, etc.
If you agree, I would like to contribute too!

Thanks!
