This is a reland of ae685e7e94fbae79334c4f1c2f296af70e041810
Original change's description:
> Add support for warming up the browser's cache but running in a fresh renderer.
> 
> Adds WARM_BROWSER and HOT_BROWSER cache temperatures to the cache_temperature
> module. These new temperatures pre-warm the browser cache in a different
> tab to the one on which the test will be run, avoiding warming the renderer's
> cache.
