Measure separate NavigationTiming metric(s) focused on Asia with higher sampling
Closed, ResolvedPublic

Description

The idea is to capture more RUM data from Asia before and after the cache pop deployment. It will need to be its own separate metric, to avoid changing our long term trends by making the sampling "uneven".

Looking at the browser data in Pivot for Asia, Chrome is very prominent, so we can afford to focus only on that browser to get some "advanced" metrics like first paint. Focusing on just one browser should also provide more stable metrics.
