Remove dependencies on k8s.io/kubernetes

[msau42]

What happened:
Packages from k8s.io/kubernetes were not designed to be imported and adds a lot of complexity to our dependency management where we need to inject "replace" statements into go.mod. It is also not supported by dependabot, which we would like to use to help automate our releases.

It looks like the dependencies are all coming from the e2e tests, which are importing the kubernetes e2e test framework libraries:

@xing-yang I think we may want to move this out to its own repo, or maybe into the csi-test repo?

@msau42 Right, we need to think about this. Maybe csi-test repo is a better choice rather than creating another repo.
