@ohltyler, Tests are flaky. Tested the failing test locally.

Let's see what we can do to get them not flaky in these test runners. Not opposed to increasing the timeout if that's the bottleneck happening.

Hi @ohltyler, fixed all the flakiness in the integration tests where-ever I noticed.

@ohltyler, shall we get this workflow merged.

LGTM!

You will probably need to do a manual backport to update the versions in the CI workflow.
