Start using std::map for Values in the statscollector. This is in preparaton for more work which will cut down on the string copying work we do.

Rename "AddValue" methods to AddXxx where Xxx is the type being added. Moving forward, we'll support those types natively without conversion to string.

Normalizing the extraction code to have fewer places that add the same stats and data driven additions to reports instead of multiple call sites.
