This yaml file uses `docker.io/alpine/socat:1.7.4.3-r0`, either we figure out
how to replace the image or just eliminate the yaml itself if it is not
being used for testing anything in this repository.
Found this when we run `e2e.test --list-images`, the dockerhub image reference
above shows up which gives a false impression that we depend on this image
for our testing purposes. Also we should NOT depend on a dockerhub image anyways!

It was possible to patch images in the YAML files via KUBE_TEST_REPO, but it
was not possible to know in advance which images might be needed. Now
-list-images also includes all images referenced by the
test-manifest/storage-csi YAML files.
