Better RUM debug data

We now keep track of debug metrics like DOMContentLoaded and the load event. In addition to that we show what render-blocking script took the longest to load.

More RUM customization

Set up page groups for analysis, limit data collection to specific domains, and configure privacy settings to control what data gets saved.

Compare tests and pages more easily
