May we also switch to junit5 as part of this effort?

Review comment:
> [hotfix][tests] Allow ZooKeeperCheckpointIDCounterITCase to loop
Out of curiosity: Is this required to run the Intellij run-until-failure
functionality? 🤔 I couldn't reproduce it. In what sense is the new code
different from the old version?

Review comment:
```suggestion
assertThat(all).last(LONG).isLessThan(counter.get());
assertThat(all).last(LONG).isLessThan(counter.getAndIncrement());
```
just playing around with the assertj API a bit here. Doesn't need to be
applied. 8)
