Title: ExternalsTracker gem

@hornairs @camilo @boourns

I wrapped up some janky monkeypatches in a gem that will enable them only when they're being listened to with a kind of pub/sub interface. See matching PR in shopify for initial usecase.

This is for the performance CI tool we spoke about yesterday.
