While helping with the 1.31 rebase, I noticed that we are skipping some e2e tests that we probably should not be. (https://github.com/openshift/kubernetes/blob/master/openshift-hack/e2e/annotate/rules.go).

Notably, we are apparently still skipping the "new" NetworkPolicy tests because of performance problems, but those problems were fixed a long time ago (the tests used to create a ton of pods, but were rewritten to reuse the same pods between tests), but we apparently never unskipped the tests. And now the legacy NetworkPolicy tests have been removed, which means we are not running any NetworkPolicy tests in our e2e...

Anyway, someone should fix that, and then go through the other networking-related skips and see if they are still relevant, and maybe convert old bugzilla bugs to Jira bugs if they are.
