Title: Website Counter Support

Contains changes that allow webiste performance to be measured by cross referencing the site name with the app pool id and w3wp process index to determine which IIS7 counters belong to which site and which w3wp counters belong to which site.

This change breaks time-range based counters (requests/sec) as counter values from previous queries are not persisted by the performance counter query engine.
