Remove "boosts" to start over

We started implementing this feature over half a year ago, and had to
stop work on it to pursue other priorities.

This removes the in-progress work so that:
- users don't see non-functional UI, and
- we can start again with a more suitable approach now that we've had
  more time to reflect on it, and more experience running Search API v2
  in production
