[Findit] Add metrics for flakes identified in waterfall analyses

Collecting metrics for flakes identified in waterfall analyses.

This data should help us to better understand
 - the number of flaky tests that Findit is able to find;
 - how good is Findit to find flakes on waterfall;
 - and we can also use the data to compare to the flake analyses and see if there are any discrepancies;
