Results:
- For now, no failures with clock-scramble nemesis + partition nemesis -> TODO long test run
- No failures with clock-scramble nemesis + db nemesis + partition nemesis (`--scenario cdp`) (0 failures in 10 runs).
- **Fails with layout reconfiguration nemesis** (`--scenario r`).
Example of a failed run: `garage set2/20231025T115033.553+0200` (2 failures in 2 runs).
- **Fails with just layout reconfiguration nemesis** (`--scenario r`).
Example of a failed run: `garage set2/20231025T141940.198+0200` (10 failures in 10 runs).
