Netdata monitor windows 8.1

[OdysLam]

@nocera, at the moment we can gather whatever metrics the Prometheus Windows exporter provides us. So the idea is that you run the exporter natively on windows and you have Netdata pulling from the exporter, either from a docker container on the windows machine, from the WSL of the same machine, or another linux system that is in the same network (as the wmi collectors uses HTTP to poll the exporter endpoint).
