ginkgo.GinkgoHelper is a recent addition to ginkgo which allows functions to
mark themselves as helper. This then changes which callstack gets reported for
failures. It makes sense to support the same mechanism also for logging.
There's also no reason why framework.Logf should produce output that is in a
different format than klog log entries. Having time stamps formatted
differently makes it hard to read test output which uses a mixture of both.
Another user-visible advantage is that the error log entry from
framework.ExpectNoError now references the test source code.
With textlogger there is a simple replacement for klog that can be reconfigured
to let the caller handle stack unwinding. klog itself doesn't support that
and should be modified to support it (feature freeze).
Emitting printf-style output via that logger would work, but become less
readable because the message string would get quoted instead of printing it
verbatim as before. So instead, the traditional klog header gets reproduced
in the framework code. In this example, the first line is from klog, the second
from Logf:
I0111 11:00:54.088957 332873 factory.go:193] Registered Plugin "containerd"
...
I0111 11:00:54.987534 332873 util.go:506] >>> kubeConfig: /var/run/kubernetes/admin.kubeconfig
Indention is a bit different because the initial output is printed before
installing the logger which writes through ginkgo.GinkgoWriter.
One welcome side effect is that now "go vet" detects mismatched parameters for
framework.Logf because fmt.Sprintf is called without mangling the format
string. Some of the calls were incorrect.
This changes the text registration so that tags for which the framework has a
dedicated API (features, feature gates, slow, serial, etc.) those APIs are
used.
Arbitrary, custom tags are still left in place for now.
Bump the timeout as the previous timeout was sometimes too short,
resulting in the pod status update not sent. Also, fixed a typo in
previous refactor.

Since the pod names are reused across the test, searching the logs is
currently difficult.
Use a uuid for each pod name to make grepping the logs easier. Also,
always include the pod name and pod namespace in any logs or error
messages to make debugging easier.

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.
Every ginkgo callback should return immediately when a timeout occurs or the
test run manually gets aborted with CTRL-C. To do that, they must take a ctx
parameter and pass it through to all code which might block.
This is a first automated step towards that: the additional parameter got added
with
sed -i 's/\(framework.ConformanceIt\|ginkgo.It\)\(.*\)func() {$/\1\2func(ctx context.Context) {/' \
$(git grep -l -e framework.ConformanceIt -e ginkgo.It )
$GOPATH/bin/goimports -w $(git status | grep modified: | sed -e 's/.* //')
log_test.go was left unchanged.

Use a watch to detect invalid pod status updates in graceful node
shutdown node e2e test. By using a watch, all pod updates will be
captured while the previous logic required polling the api-server which
could miss some intermediate updates.

Revert to previous behavior in 1.21/1.20 of setting pod phase to failed
during graceful node shutdown.
Setting pods to failed phase will ensure that external controllers that
manage pods like deployments will create new pods to replace those that
are shutdown. Many customers have taken a dependency on this behavior
and it was breaking change in 1.22, so this change reverts back to the
previous behavior.

* 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.

- Test was failing due to using `sleep infinity` inside the busybox
container which was going into a crash loop. `sleep infinity` isn't
supported by the sleep version in busybox, so replace it with a `while
true; sleep loop`.
- Replace usage of dbus message emitting from gdbus to dbus-send. The
test was failing on ubuntu which doesn't have gdbus installed.
dbus-send is installed on COS and Ubuntu, so use it instead.
- Replace check of pod phase with the test util function `PodRunningReady`
which checks both phase as well as pod ready condition.
- Add some more verbose logging to ease future debugging.
