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.
Part of efforts to clean up mentions of rkt in kubelet.
rkt was removed entirely in 1.11, in favor of using `rktlet` and CRI
instead. It should no longer be listed at all as a runtime.
This commit is part of a larger effort to clean up references to `rkt`
in the kubelet.
Previously, this comment hard-coded which integrations required
the cadvisor stats provider. The comment has grown stale
(i.e. referenced rkt and did not reference cri-o).
Update the comment to instead point to the code which determines which
integrations need the cadvisor stats provider.
The `FakeDockerClient` had a number of methods defined on it which were
not being called anywhere. The majority were of the form `Assert...`.
In the spirit of removing dead code, remove the methods which aren't
being called.
