Changes

With this change, we are disabling them in the PR - Optional step. We will still be able to notice performance regressions from the performance tests, so we're not losing much test coverage.

Reason

These tests have been failing consistently in our CI for as long as I can remember. While each individual test false positive rate is not high, the fact that we run many of them in a multitude of combinations means that at every CI run at least one fails.

I still think we should just delete the python test altogether

While I see your point, and how this test could become stale, I'm thinking how we'd run these benchmark on all instances if we needed in the future. Having this test in the codebase would save up some time, as it'd be just a manual test run through BK, and it's not trivial to replicate what this python file does.

These tests have been failing consistently in our CI for as long as I
can remember. While each individual test false positive rate is not
high, the fact that we run many of them in a multitude of combinations
means that at every CI run at least one fails.

With this change, we are removing them from the PR - Optional step. We
will still be able to notice performance regressions from the
performance tests, so we're not losing much test coverage.
