Summary: This class contains metrics about RN bridge startup that was being sent via FBAnalytics. This diff refactors out any timespans being collected into a separate method. This refactor is NOT ENOUGH to format the data into a format QPL accepts. I still need to refactor these timespans into _start and _end points for QPL points to work correctly. This diff is a starting point. Reviewed By: ejanzer Differential Revision: D10466982 fbshipit-source-id: 4bc1159c4e53328f2252a8c606c8d6ff8d657489
