John Spray 7cbb39063a tests: stabilize + extend deletion queue recovery test (#5457) ...

## Problem

This test was unstable when run in parallel with lots of others: if the
pageserver stayed up long enough for some of the deletions to get
validated, they won't be discarded on restart the way the test expects
when keep_attachment=True. This was a test bug, not a pageserver bug.

## Summary of changes

- Add failpoints to control plane api client
- Use failpoint to pause validation in the test to cover the case where
it had been flaky
- Add a metric for the number of deleted keys validated
- Add a permutation to the test to additionally exercise the case where
we _do_ validate lists before restart: this is a coverage enhancement
that seemed sensible when realizing that the test was relying on nothing
being validated before restart.
- the test will now always enter the restart with nothing or everything
validated.
