Prometheus and WMI CounterTypes

Prometheus and WMI CounterTypes

WMI performance counters hava many types, and those need to be mapped to Prometheus' types. Below is a listing of WMI types, the Prometheus type that should be used, and any processing that needs to be done.

This applies to WMI classes inheriting Win32_PerfRawData.
