The test got broken to not actually use "no cluster CIDR" when
LocalDetector was implemented (and the old version of the unit test
didn't check enough to actually notice this).
The original tests here were very shy about looking at the iptables
output, and just relied on checks like "make sure there's a jump to
table X that also includes string Y somewhere in it" and stuff like
that. Whereas the newer tests were just like, "eh, here's a wall of
text, make sure the iptables output is exactly that". Although the
latter looks messier in the code, it's more precise, and it's easier
to update correctly when you change the rules. So just make all of the
tests do a check on the full iptables output.
(Note that I didn't double-check any of the output; I'm just assuming
that the output of the current iptables proxy code is actually
correct...)
Also, don't hardcode the expected number of rules in the metrics
tests, so that there's one less thing to adjust when rules change.
Also, use t.Run() in one place to get more precise errors on failure.
The test was sorting the iptables output so as to not depend on the
order that services get processed in, but this meant it wasn't
checking the relative ordering of rules (and in fact, the ordering of
the rules in the "expected" string was wrong, in a way that would
break things if the rules had actually been generated in that order).
Add a more complicated sorting function that sorts services
alphabetically while preserving the ordering of rules within each
service.
This makes it consistent with klog's text output and avoids polluting the
programs normal output with log messages. This may become relevant for command
line tools like "kubectl".
Instead of the individual error and return, it's better to aggregate all
the errors so that we can fix them all at once.
Take the chance to fix some comments, since kubeadm are not checking that
the certs are equal across controlplane.

* Bump the pod status and node status update timeouts to avoid flakes
* Add a small delay after dbus restart to ensure dbus has enough time to
restart to startup prior to sending shutdown signal
* Change check of pod being terminated by graceful shutdown. Previously,
the pod phase was checked to see if it was `Failed` and the pod reason
string matched. This logic needs to change after 1.22 graceful node
shutdown change introduced in PR #102344 which changed behavior to no
longer put the pods into a failed phase. Instead, the test now checks
that containers are not ready, and the pod status message and reason
are set appropriately.

It looks like it tests two pods sharing the same volume, but the goal is
actually the opposite - two pods with the same inline volume definition
should get separate volumes.
In various places log messages where emitted as part of validation or even
before it (for example, cli.PrintFlags). Those log messages did not use the
final logging configuration, for example text output instead of JSON or not the
final verbosity. The last point became more obvious after moving the setup of
verbosity into logs.Options.Apply because PrintFlags never printed anything
anymore.
In order to force applications to deal with logging as soon as possible, the
Options.Validate and Options.Apply methods are now private. Applications should
use the new Options.ValidateAndApply directly after parsing.
