Adding two .com metrics to operating metrics page
@jeremy we in the process of creating definitions for all metrics that we report on for the investor update, plus more. I've added the below metrics, but these metrics will need to live in the respective handbook for next iteration along with an update of more formal, articulate definitions. The operating metrics page is going away and the metrics that we track will be found in the data teams kpi page. The data team kpi page will be the landing page for all metrics. The metrics themselves will live in the respective handbook.
