If the container was already cleaned up we should not try to do it
again. Podman stop will always try to call Cleanup() if you look at the
podman event log and just keep calling podman stop --all you see a
cleanup event every time. This is not wanted. Also in case of the host
pidns we report a error every single time, see the linked issue.

initContainers in kubernetes deployments had no call to CompleteSpec in the
generation, which means that the default environment is not configured for
these. This causes issues with missing default environment variables like $HOME
or $PÄTH.
Also, switch to using logrus.Warn() instead of fmt.Fprintf(os.Stderr)
This fixes https://github.com/containers/podman/issues/18384

This one got complicated, and deserves its own commit.
Problem: ginkgo logs have a lot of NUL characters, making them
difficult for logformatter to process and for humans to read.
Cause: Paul tracked it down to "podman volume export" without "-o"
(hence spitting out tar data to stdout).
Solution: add "-o tmpfile" to named podman-volume-export. In
the process, fix all sorts of other problems with that test.
And, since the e2e test no longer tests "volume export" by
itself, add a system test that does.
It is possible that there are other places that emit NULs.
One step at a time.

- fix a typo that was resulting in a test being a NOP, and
add actual testing to it.
- fix two Expects() with incorrectly-ordered actual/expects
- remove leading whitespace from an It() test name
- To(BeTrue()) is evil. Wherever possible, replace it with
useful string or field checks. When not possible, use
the annotation field to indicate what failed. I got
carried away here, #sorrynotsorry
- remove unused system-test code

Podman kube generate now uses the pod's restart policy
when generating the kube yaml. If generating from containers
only, use the restart policy of the first non-init container.
Podman kube play applies the pod restart policy from the yaml
file to the pod. The containers within a pod inherit this restart
policy.

Add --restart flag to pod create to allow users to set the
restart policy for the pod, which applies to all the containers
in the pod. This reuses the restart policy already there for
containers and has the same restart policy options.
Add "never" to the restart policy options to match k8s syntax.
It is a synonym for "no" and does the exact same thing where the
containers are not restarted once exited.
Only the containers that have exited will be restarted based on the
restart policy, running containers will not be restarted when an exited
container is restarted in the same pod (same as is done in k8s).

This never worked when ginkgo runs with more than one thread, we use 3
in CI. The problem is that the SynchronizedAfterSuite() function accepts
two functions. The first one is run for each ginkgo node while the
second one is only run once for the whole suite.
Because the timings are stored as slice thus in memory we loose all
timings from the other nodes as they were only reported on node 1.
Moving the printing in the first function solves this but causes the
problem that the result is now no longer sorted. To fix this we let
each node write the result to a tmp file and only then let the final
after suite function collect the timings from all these files, then
sort them and print the output like we did before.

Just like Cleanup() they should check the error codes.
While doing this it was clear that some volume tests were calling
Cleanup() twice so remove this.
Instead make sure they call Cleanup() themselves so callers only need to
do one call. This is required because we cannot use Expect().To() before
doing all the cleanup. An error causes panic does results in an early
return thus missing potentially important cleanup.

It looks like AfterEach() is now executed even after Skip(), this is a
good idea because the fact that it did't before caused us to leak tmp
directories. However in case Skip() is called before the podmanTest is
initialized it will no result in a panic. To fix it simply prevent such
panic by checking the pointer against nil and do nothing in such case.

Directly writing to stdout/err is not safe when run in parallel.
Ginkgo v2 fixed this buffering the output and syncing the output so it
is not mangled between tests.
This means we should use the GinkgoWriter everywhere to make sure the
output stays in sync.

The test will leak processes because the rm -fa in the cleanup failed.
This happens because podman tried to remove the contianers in the wrong
order and thus ppodman failed with:
`contianer XXX has dependent containers which must be removed before it`
For now I patch the test but it should be much better if we can fix it
in podman to remove in the correct order. `--all` should mean all I do
not care if there is a dependent container, just get rid of it.

We blindy trust these commands to work but as it turns out they do not
under certain circumstances.
The "podman run ipcns ipcmk container test" can be used to fail this
reliably, if a container has dependencies the order of rm --all may
cause it to fail because the contianers are deleted in the wrong order.
This is th eonly one I found so far, adding this will uncover many more
of such problems without proper cleanup we leak processes and ginkgo v2
will block because of them.
Of course this cannot be merged without fixing these issues.

This is not safe at all when run in parallel, CNI needs that directory
to detect duplicated ips and also stores other important network info in
it. Removing it while container network is setup is not safe at all and
could cause a lot of weird flakes.
This "hack" was added in commit 55508c11 but provides zero context what
this was supposed to fix so I don't know what the actual issue is or was.

Podman's container-name generation depends on the global RNG state being
properly initialized (seeded). Should this not happen for some reason
(or it's seeded with a static value), podman will generate the exact
same repeating sequence of container names (assuming no clashes with
existing containers). Add a test to confirm this is always the case.

Note: For `runtime_test.go`, this test-case was never actually doing

require incredibly libpod-invasive changes. Do the least-worse thing and

Systemd supports unit files with a prefix '-' which
tells the system to check if the content exists before
using it. This would allow the QM project to specify
AddDevice=-/dev/kvm, which would add the /dev/kvm device

...at least as many as possible. "run/exec -it" make no sense
in a CI environment; I believe the vast majority of these are
the result of fingers typing on autopilot, then copy/pasting
cascades from those. This PR gets rid of as many -it/-ti as
possible. Some are still needed for testing purposes.
Y'all have no idea how much I hate #10927 (the "no logs from conmon"
flake). This does not fix the underlying problem, nor does it even
eliminate the flake (The "exec terminal doesn't hang" test needs
to keep the -ti flag, and that's one of the most popular flakers).
But this at least reduces the scope of the problem. It also removes
a ton of nasty orange "input device is not a TTY" warnings from logs.

Our friend #7096 is still not fixed: it continues to flake,
singletons only, and only in the "create" test (not "run").
My guess: maybe there's a race somewhere in IP assignment,
such that container1 can have an IP, but not yet be running,
and a container2 can sneak in and start with that IP, and
container1 is the one that fails?
Solution: tighten the logic so we wait for container1 to
truly be running before we start container2. And, when we
start container2, do so with -a so we get to see stdout.
(Am not expecting it to be helpful, but who knows).
Also very minor cleanup
