There is a race condition in the signal handling which manifests itself
as flake in our CI.
In short the old code was running the signal handler in a goroutine but
never waited for it to be finished the main routine just waits for the
container exit so it was possible the process exits in PlayKubeDown()
between the PodStop and PodRm calls. So the container/pod was leaked and
thus the test fails.
This can be easily reproduced by adding a sleep there.
To fix this properly we use a wait group to ensure the goroutine is
finished before we exit. Then there is also no need for the extra bool
and teardown on the non signal path. We can just close the channel there
and cleanup via the signal goroutine which will always fire when the
channel is closed.

Problem: While removing cgroupsv1 code, I noticed my neovim Go config
automatically changed fileperms to the new octal format and I didn't
want that polluting my diffs.
Decision: I thought it best to switch to the new octal format in a dedicated PR.
Action:
- Cursor switched to new octal format for all fileperm ocurrences in Go
source and test files.
- vendor/, docs/ and non-Go files were ignored.
- Reviewed manually.

The PodmanOptionsKey is never used anywhere so it is pointless to add
this. Second having several functions to return the same context makes
no sense so fold them all into one. Lastly create the context once and
always return the same one instead of having to nil check each time.

The pod was set after we checked the namespace and the namespace code
only checked the --pod flag but didn't consider --pod-id-file option.
As such fix the check to first set the pod option on the spec then use
that for the namespace. Also make sure we always use an empty default
otherwise it would be impossible in the backend to know if a user
requested a specific userns or not, i.e. even in case of a set
PODMAN_USERNS env a container should still get the userns from the pod
and not use the var in this case. Therefore unset it from the default
cli value.
There are more issues here around --pod-id-file and cli validation that
does not consider the option as conflicting with --userns like --pod
does but I decided to fix the bug at hand and don't try to fix the
entire mess which most likely would take days.

Adds a `--no-trunc` flag to `podman kube generate` preventing the
annotations from being trimmed at 63 characters. However, due to
the fact the annotations will not be trimmed, any annotation that is
longer than 63 characters means this YAML will no longer be Kubernetes
compatible. However, these YAML files can still be used with `podman
kube play` due to the addition of the new flag below.

Implement means for reflecting failed containers (i.e., those having
exited non-zero) to better integrate `kube play` with systemd. The
idea is to have the main PID of `kube play` exit non-zero in a
configurable way such that systemd's restart policies can kick in.
When using the default sdnotify-notify policy, the service container
acts as the main PID to further reduce the resource footprint. In that
case, before stopping the service container, Podman will lookup the exit
codes of all non-infra containers. The service will then behave
according to the following three exit-code policies:
- `none`: exit 0 and ignore containers (default)
- `any`: exit non-zero if _any_ container did
- `all`: exit non-zero if _all_ containers did
The upper values can be passed via a hidden `kube play
--service-exit-code-propagation` flag which can be used by tests and
later on by Quadlet.
In case Podman acts as the main PID (i.e., when at least one container
runs with an sdnotify-policy other than "ignore"), Podman will continue
to wait for the service container to exit and reflect its exit code.
Note that this commit also fixes a long-standing annoyance of the
service container exiting non-zero. The underlying issue was that the
service container had been stopped with SIGKILL instead of SIGTERM and
hence exited non-zero. Fixing that was a prerequisite for the exit-code
propagation to work but also improves the integration of `kube play`
with systemd and hence Quadlet with systemd.

Commit 2f29639bd3 added a UX improvement to cleanup/teardown when
running the specified YAML has failed. However, the teardown happens
unconditionally such that rerunning the same YAML file will teardown the
previously created workload instead of just failing with a name-conflict
error (e.g., "pod already exists"). The regression popped up testing
the Ansible system role with Podman v4.4.0.
For now, do not teardown at all on error to quickly fix this regression
for the upcoming Podman v4.4.1 release. The UX improvement is still
desired but must be conditional and only happen on newly created
resources, which probably requires moving it down to the backend.

Reasoning
---------
When the log-driver is passthrough, the journal socket is passed to the containers as-is which has two advantages:
1. journald can see who the actual sender of the log event is,
rather than thinking everything comes from the conmon process
2. conmon will not have to copy all the log data
Code Changes
------------
If log-driver was not set by the user and service-container is set use
passthrough as the default log-driver
Update the system tests
- explicitly set logdriver in sdnotify and play tests
- podman-kube template test: Verify the default log driver for service-container
