Run Member tests in parallel

[AwesomePatrol]

On my local machine it brings down execution time from 5 minutes to 32s.

I added a port allocator which allocates ports in 11000-19000 range.

Issue: #18983

Hi @AwesomePatrol. Thanks for your PR.

I'm waiting for a etcd-io member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes-sigs/prow repository.

In addition to this, have you considered using paralleltest ?

In addition to this, have you considered using paralleltest ?

Thanks for your suggestion. Running tests in parallel requires more changes than just adding t.Parallel() calls. I would prefer to keep it optional until it becomes that simple (requires refactoring a few more tests/frameworks).
