#275 RFE: pminfo option to indicate which metrics are actually available (an inverse of -v option) ( https://github.com/performancecopilot/pcp/issues/275 )

pminfo lists out the metrics it knows about on a machine. However, not all of these metrics work on a particular machine. "pminfo -v" will list which metrics don't work machine. It would be nice to have a inverse option (maybe call it --survey) to list which metrics will provide values on the particular machine, taking the "-f" option data and just listing the metrics that were successful fetched and discarding the data.
