Is the change well baked/verified in canary and overall safe to merge to M69? Also could you pls justify the merge. Thank you.

Rationale - moves some constants to finch scoring params so we can control omnibox scoring results at a finer grain after launch.
 
It's safe and contained, and behind a flag, but the API that this code exercises isn't quite public yet so it's been unexercised by end users and will continue to be until that ships (very soon) and we can enable via finch.

Approving merge to M69 branch 3497 based on comment #6. Please merge ASAP. 

Please merge your change to M69 branch 3497 by 4:00 PM PT, Monday (08/06) so we can pick it up for next week M69 beta release. Thank you.
