UPSTREAM: <carry>: support feature gate filtering from upstream

When considering upstream feature gates, not all are known or present in
openshift/api, so we have to be selective about which we filter on.

This uses data provided by OTE and an allow list to include/exclude
upstream tests.

$ k8s-tests-ext list tests --platform aws --feature-gate VolumeAttributesClass |\
  jq '.[].name' | grep VolumeAttributesClass | wc -l
30
$ k8s-tests-ext list tests --platform aws |\
  jq '.[].name' | grep VolumeAttributesClass | wc -l
       0
