The most interesting aspect of the new Ginkgo is tweaking the output so that
it's easier to follow while a job runs in
Prow (onsi/ginkgo#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.

The latest pprof added an indirect dependency on github.com/mailru/easyjson
when adding a complex integration test. This does not affect Kubernetes and
thus can be ignored.

We typically have plenty of skipped tests in an E2E run, which causes Ginkgo to
print many S characters (one for each skipped test). This easily fills up an entire
console window. Now the default is to silence that
output. GINKGO_SILENCE_SKIPS=n reverts to the previous behavior.

By default, Ginkgo prints all progress characters (S and o) in a single
line. Buffering in Prow causes that output to occur only after the run is over,
which defeats the purpose of having those characters. Now a newline is added
after each character, so there is visible progress in Prow while Ginkgo runs.

When the user manually sets either focus, skip or (new!) label filter, then the
framework should not interfere and add the default skip strings.
