Endless loop of Query [...] is not prepared [...], preparing before retrying executing.

On this execution of integration tests: https://github.com/avelanarius/java-driver/runs/6175179427?check_suite_focus=true tests running against 5.0.rc3 and 2022.1.rc3 got stuck on an endless loop of:

This test might be flaky, as I believe that 5.0.rc3 passed correctly before.

I am not able to reproduce the issue locally, but thankfully running it a couple times on GitHub Actions (all tests - not only the offending one) is able to reproduce the problem.

Closing as Dup of https://github.com/scylladb/scylladb/issues/10440 and #126 will take care of client side hardening.
