Short description in man pages:
* Use imperative form
Command help (cobra.Command.Short):
* Capitalize first letter
* Use imperative form
* Remove ending full stop when the short description
only contains one sentence without any commas
Command help (cobra.Command.Long):
* Capitalize first letter unless the sentence starts
with a command "podman command ..."
* Use imperative form when the long description is
identical or almost identical to the short description.
This modification was only done in a few places.
Command tables:
* Use imperative form in the "Description" column

Work around a go-md2man bug, and add a check script to make sure
this doesn't hit us again.
Background: go-md2man can't deal with a left-hand column > 31 chars.
It produces man pages that look like:
| Something With >31 Character | |
| | ..description |
(should be all on one row). It also has trouble when the vertical
bars are misaligned: it completely removes the right-hand side.
There's almost certainly a better solution: fix go-md2man, or
use a different conversion tool, or maybe even pre/postprocess.
But this is a quick interim solution.
Sorry for the perl. This could be done in bash/sed/awk/grep,
but not with any sort of sane error messages.

Add a new field `ExitCodePropagation` field to allow for configuring the
newly added functionality of controlling how the main PID of a kube
service exits.

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.

Make sure to look for the container's exit code when it's in stopped
state. With `--restart=always`, the container seems to stay in the
stopped state which led the wait logic to loop until the 20 seconds
timeout for the cleanup process to have finished kicks in.
Also defensively make sure to loop when the container is in stopped
state but no exit code has been written yet.
Add a regression test to make sure Podman doesn't wait more than 20
seconds. Even on a CI machine under high load I expect it to take much
much much less than that, so I do not expect this test to flake in the
future.

the combination --pod and --userns is already blocked. Ignore the
PODMAN_USERNS variable when a pod is used, since it would cause to
create a new user namespace for the container.
Ideally a container should be able to do that, but its user namespace
must be a child of the pod user namespace, not a sibling. Since
nested user namespaces are not allowed in the OCI runtime specs,
disallow this case, since the end result is just confusing for the
user.

The `--network-cmd-path` CLI option only affects rootless networks using `slirp4netns(1)`, not `pasta(1)`. Following #18568 Podman should rather use the more generic `r.config.FindHelperBinary()` method (and therefore honour the `helper_binaries_dir` config) to find the path to the `slirp4netns` binary and deprecate the misleading `--network-cmd-path` CLI option. However, since this wasn't implemented yet we can't deprecate `--network-cmd-path` as of now. Adding a note anyway.

I would like to allow admin to control quadlet containers
in users homedirs.
If an admin sets a quadlet in
/etc/containers/systemd/users, then all users will run these
quadlet services when they login.
If an admin places a quadlet in /etc/containers/systemd/users/$(USERNAME)
then only the USERNAME will execute this quadlet service when
they login.

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).

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
to the container iff it exists on the host.
