Ginkgo v2.18.0 allows tweaking the output so that it's easier to follow while a job runs in Prow (https://github.com/onsi/ginkgo/issues/1347). Using this in hack/ginkgo-e2e.sh will follow in a separate commit. Gomega gets bumped to the latest release to keep it up-to-date. Ginkgo v1.19.0 adds support for --label-filter with labels that represent sets (like our Feature:<Foo>).
