KEP-3041 - Tracking Work

[kannon92]

What would you like to be added:

As part of https://github.com/kubernetes/enhancements/tree/master/keps/sig-testing/3041-node-conformance-and-features, I would like to work on cleaning up our test-infra for sig-node.
Why is this needed:

Testing is hard enough and we have so many labels that are not necessary used. Let's try and move all special labels to feature at the moment.
