Clare Ming eb597645c3 Refactor TOC A/B test to bucket users on backend
- Include temporary feature requirement for TOC A/B test.
  - Assumes 100% of logged-in users with even/odd user ids
  being assigned to treatment/control buckets respectively.
  - Sampling rates passed in by config are not considered
  during bucketing.
- Update hook for adding needed TOC A/B test body classes.
- Add test for temp feature.

Note: the temporary feature requirement and associated hooks
should be removed once the 2nd TOC A/B test concludes.
