tests: Too long timeout - test fails after 6+ minutes

[nirs]

I'm not sure what is the purpose of TestFunctionalNewestKubernetes/Versionv1.35.0-beta.0/parallel/PersistentVolumeClaim but there is no reason why the test should fail after 6 minutes.

Checking the logs shows that it failed because the known rate-limit issue, but it is not clear why we need to pull nginx image for testing a PVC.

We need to minimize the test timeout so it fails quickly.

@nirs can we pull an image from github container registry instead ? to avoid all that ?

I have a feeling there should be a good way to Detect Api Rate limit
I think there is a "curl" we can do before the tests to check how many Rate limit quota we have left and if it is near 0 we should just Not Run the test... and Fail with a Nice message (will not run test)
