This is currently the top flake against PRs, so I'm tagging it
as [Flaky]. Flaky tests can't be conformance tests, so I'm
removing it from [Conformance] as well until this is resolved.
it turns out that the e2e test was not using the timeout used to
hold the CLOSE_WAIT status, hence the test was flake depending
on how fast it checked the conntrack table.
This PR replaces the dependency on ssh using a pod to check the conntrack
entries on the host in a loop, to make the test more robust
and reduce the flakiness due to race conditions and/or ssh issues.
It also fixes a bug trying to grep the conntrack entry, where
the error was swallowed if a conntrack entry wasn't found.
It seems that the Image Promoter is running containers without the -t flag, which causes the error:
the input device is not a TTY
Removing the -it from the docker command in kubernetes/test/images/image-util.sh solves this.
Issue: https://github.com/kubernetes/kubernetes/issues/86884
This PR fixes the issue that err variable gets shadowed. Because of
this, it might get nil pointer error.

Prior to the Image Centralization part 4 (https://github.com/kubernetes/kubernetes/pull/81170),
a PR merged that enables the Image Promoter to run on the k/k test images.
The Image Promoter currently only builds the Conformance-related images, but the
Image Centralization part 4 centralized some of those images into agnhost, so they
need to be removed from the conformance_images list.
Additionally, https://github.com/kubernetes/kubernetes/pull/81226 proposes mounttest-user
image to be removed, and RunAsUser to be used in tests instead.
The image used by the Image Promoter (gcr.io/k8s-testimages/gcb-docker-gcloud:v20190906-745fed4)
is based on busybox, and thus, the sed binary is actually busybox. image-util.sh calls
kube::util::ensure-gnu-sed several times, which ensures that a GNU sed binary exists
(it checks by greping GNU in its --help output). Obviously, it won't match the busybox sed
binary. But the sed usage in image-util.sh is fairly simple, and the busybox sed is sufficient.
Bumps image versions for: jessie-dnsutils, nonewprivs, resource-consumer, sample-apiserver. These
images are included in the conformance_images that are being built by the Image Promoter, so
we're bumping them just to make sure we're not breaking anything and cause all the CIs to fall.
We're going to bump the image versions used in tests in a subsequent PR. The image version was not
bumped for: agnhost, kitten, nautilus, as they were already bumped by the Image Centralization part 4
PR.
