Disable submodules and increase timeout to prevent #4797 that uses testdata from flaking.

Hi @annasong20. Thanks for your PR.

I'm waiting for a kubernetes-sigs 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/test-infra repository.

Do you mind giving the commit a better message and the PR a better title? This becomes part of the release notes...

Edited to add: Actually we'll probably remove this from the release notes anyways so it doesn't actually matter, never mind
