Does not fill sensors.
*Analysis*
This is happening because std err is appearing in winrm response of the
command. Stderr looks like this.

I think it is not harmful and can be turned of by adding {{$ProgressPreference
= "SilentlyContinue";}} in front of the poll command which is built in
{{preStart}} of {{WindowsPerformanceCounterFeed}}.
Approach I described makes {{WindowsPerformanceCounterFeed}} happy and it
displays results. Will submit a PR.
