Add a node e2e to verify that if a static pod is terminated while the
container runtime or CRI returns an error, the pod is eventually
terminated successfully.
This test serves as a regression test for k8s.io/issue/113145 which
fixes an issue where force deleted pods may not be terminated if the
container runtime fails during a `syncTerminatingPod`.
To test this behavior, start a static pod, stop the container runtime,
and later start the container runtime. The static pod is expected to
eventually terminate successfully.
To start and stop the container runtime, we need to find the container
runtime systemd unit name. Introduce a util function
`findContainerRuntimeServiceName` which finds the unit name by getting
the pid of the container runtime from the existing
`ContainerRuntimeProcessName` flag passed into node e2e and using
systemd dbus `GetUnitNameByPID` function to convert the pid of the
container runtime to a unit name. Using the unit name, introduce helper
functions to start and stop the container runtime.

The recently introduced failure handling in ExpectNoError depends on error
wrapping: if an error prefix gets added with `fmt.Errorf("foo: %v", err)`, then
ExpectNoError cannot detect that the root cause is an assertion failure and
then will add another useless "unexpected error" prefix and will not dump the
additional failure information (currently the backtrace inside the E2E
framework).
Instead of manually deciding on a case-by-case basis where %w is needed, all
error wrapping was updated automatically with
sed -i "s/fmt.Errorf\(.*\): '*\(%s\|%v\)'*\",\(.* err)\)/fmt.Errorf\1: %w\",\3/" $(git grep -l 'fmt.Errorf' test/e2e*)
This may be unnecessary in some cases, but it's not wrong.
WaitForPodToDisappear was always called such that it listed all pods, which
made it less efficient than trying to get just the one pod it was checking for.
Being able to customize the poll interval in practice wasn't useful, therefore
it can be replaced with WaitForPodNotFoundInNamespace.

All code must use the context from Ginkgo when doing API calls or polling for a
change, otherwise the code would not return immediately when the test gets
aborted.

This is gross but because NewDeleteOptions is used by various parts of
storage that still pass around pointers, the return type can't be
changed without significant refactoring within the apiserver. I think
this would be good to cleanup, but I want to minimize apiserver side
changes as much as possible in the client signature refactor.
Contination of #1111
I tried to keep this PR down to just a simple search-n-replace to keep
things simple. I may have gone too far in some spots but its easy to
roll those back if needed.
I avoided renaming `contrib/mesos/pkg/minion` because there's already
a `contrib/mesos/pkg/node` dir and fixing that will require a bit of work
due to a circular import chain that pops up. So I'm saving that for a
follow-on PR.
I rolled back some of this from a previous commit because it just got
to big/messy. Will follow up with additional PRs
