Clean up static-ip in e2e

I dropped this line: https://github.com/kubernetes/kubernetes/pull/35331/files#diff-5997d488011ead8354bdddfceaf1515dL595, in a previous refactor https://github.com/kubernetes/kubernetes/pull/35331, so we started leaking static ips. This commit adds it back in, along with some debug info if it happens again. Marking p2 since test is currently leaking.
