"Total Site" metrics should be made available in Report Builder

[#1]

"Total Site" metrics should be supported within the ReportBuilder API, so metric containing the metric will be available within ReportBuilder. I have features like bounce rate for the entire website that is going to be very complex to set up including a lot of manually work each month.

Total Site Metrics is available from the metrics drop-down selector in the ReportBuilder request wizard.
