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.

The metrics should start coming in when the NavTiming code gets gradually deployed with the train.
Geo.region doesn't contain the continent.
We need to use that kind of mapping: https://github.com/wikimedia/puppet/blob/production/modules/webperf/files/navtiming.py#L27
