The NPD test checks when NPD started to determine if it is needed to
check the kubelet start event. The current logic requires parsing the
journalctl logs which is quite fragile and is broken now because of
systemd changing the expected log format.
Newer versions of systemd do not print "end at" or "logs begin at" and
instead may print "No entries", which will result in the test panicking.
```
$ journalctl -u foo.service
-- No entries --
```
For units started, it will not print "end at" or "logs begin at":
```
root@ubuntu-jammy:~# journalctl -u foo.service
Feb 08 22:02:19 ubuntu-jammy systemd[1]: Started /usr/bin/sleep 1s.
Feb 08 22:02:20 ubuntu-jammy systemd[1]: foo.service: Deactivated successfully.
```
To avoid relying on log parsing which is fragile, let's instead directly
ask systemd when the NPD service started and parse the resulting
timestamp.

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.
NPD can run in "standalone" or "daemonset" mode in cluster GCE tests.
For standalone mode, NPD runs as a systemd unit, daemonset mode it runs
as pod.
If NPD is running in standalone mode, as soon as we detect that the npd
service does not exist with `systemctl status`, we should skip the rest
of the checks such as looking at the journalctl logs or pid.

Fix the `staticcheck` failures for `test/e2e/node`. All of the
staticcheck errors were for variables which were never used. When these
values were `err`, we added processing for the errors. When they were
values that were just never used, we stopped giving them a name.
Remove the "OrDie" from the name (since it doesn't "or die") and add
an extra check that there is at least 1 node available, since many
callers already did that themselves, and many others should have.
There are some functions of e2e test framework and it is useful to
read the test code by using these functions.
This replaces gomega calls with these functions under test/e2e/node/
A number of tests rely on SSH behavior but are not marked with
SkipUnlessSSHKeysPresent(). This means that the tests will run and
hang. This can be confusing for users because they may not know why
the tests failed. Instead, we should be reporting on the known issue
and skipping the test (hence why the helper Skip... function exists).
- Add a package "node" under e2e/framework and alias e2enode;
- Rename some functions whose name have redundant string.

The framework/ssh.go code was heavily used throughout the framework
and could be useful elsewhere but reusing those methods requires
importing all of the framework.
Extracting these methods to their own package for reuse.
Only a few methods had to be copied into this package from the
rest of the framework to avoid an import cycle.
This is part of the transition to using framework/log instead
of the Logf inside the framework package. This will help with
import size/cycles when importing the framework or subpackages.
