Refactor the page issues A/B test logging implementation to a distinct
new file that only has the responsibility of tracking.
T191528 is referenced in this commit as I was having difficulty
answering the feedback and bugs reported in the current implementation
without working through and restructuring the flow as I understood it.
This refactor is merely a byproduct artifact of that effort to focus on
the parsing and presentation responsibilities.
Bug: T191528

The hook that enables the Reading depth test should send an
additional paramter that specifies which test bucket the hook
being is calling from.

Provides a class that initiates AB-test bucketing and registers
as a MF module. Activates the reading depth test for users who are bucketed
in either buckets "A" or "B".
Does not add event-logging or visual style changes for page issues AB test.
