GoLang sets unset values to the default value of the type. This means that the destination of the log is an empty string and the count and size are set to 0. However, this means that size and count are unbounded, and this is not the default behavior.

Undoing some of my own work here from #24090 now that we have the
ExposedPorts field implemented in inspect. I considered a revert
of that patch, but it's still needed as without it we'd be
including exposed ports when --net=container which is not
correct.
Basically, exposed ports for a container should always go in the
new ExposedPorts field we added. They sometimes go in the Ports
field in NetworkSettings, but only when the container is not
net=host and not net=container. We were always including exposed
ports, which was not correct, but is an easy logical fix.
Also required is a test change to correct the expected behavior
as we were testing for incorrect behavior.

Previously, we didn't bother including exposed ports in the
container config when creating a container with --net=host. Per
Docker this isn't really correct; host-net containers are still
considered to have exposed ports, even though that specific
container can be guaranteed to never use them.
We could just fix this for host container, but we might as well
make it generic. This patch unconditionally adds exposed ports to
the container config - it was previously conditional on a network
namespace being configured. The behavior of `podman inspect` with
exposed ports when using `--net=container:` has also been
corrected. Previously, we used exposed ports from the container
sharing its network namespace, which was not correct. Now, we use
regular port bindings from the namespace container, but exposed
ports from our own container.

These flags can affect the output of the HealtCheck log. Currently, when a container is configured with HealthCheck, the output from the HealthCheck command is only logged to the container status file, which is accessible via `podman inspect`.
It is also limited to the last five executions and the first 500 characters per execution.
This makes debugging past problems very difficult, since the only information available about the failure of the HealthCheck command is the generic `healthcheck service failed` record.
- The `--health-log-destination` flag sets the destination of the HealthCheck log.
- `none`: (default behavior) `HealthCheckResults` are stored in overlay containers. (For example: `$runroot/healthcheck.log`)
- `directory`: creates a log file named `<container-ID>-healthcheck.log` with JSON `HealthCheckResults` in the specified directory.
- `events_logger`: The log will be written with logging mechanism set by events_loggeri. It also saves the log to a default directory, for performance on a system with a large number of logs.
- The `--health-max-log-count` flag sets the maximum number of attempts in the HealthCheck log file.
- A value of `0` indicates an infinite number of attempts in the log file.
- The default value is `5` attempts in the log file.
- The `--health-max-log-size` flag sets the maximum length of the log stored.
- A value of `0` indicates an infinite log length.
- The default value is `500` log characters.

This started off as an attempt to make `podman stop` on a
container started with `--rm` actually remove the container,
instead of just cleaning it up and waiting for the cleanup
process to finish the removal.
In the process, I realized that `podman run --rmi` was rather
broken. It was only done as part of the Podman CLI, not the
cleanup process (meaning it only worked with attached containers)
and the way it was wired meant that I was fairly confident that
it wouldn't work if I did a `podman stop` on an attached
container run with `--rmi`. I rewired it to use the same
mechanism that `podman run --rm` uses, so it should be a lot more
durable now, and I also wired it into `podman inspect` so you can
tell that a container will remove its image.
Tests have been added for the changes to `podman run --rmi`. No
tests for `stop` on a `run --rm` container as that would be racy.

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.

For systems that have extreme robustness requirements (edge devices,
particularly those in difficult to access environments), it is important
that applications continue running in all circumstances. When the
application fails, Podman must restart it automatically to provide this
robustness. Otherwise, these devices may require customer IT to
physically gain access to restart, which can be prohibitively difficult.
Add a new `--on-failure` flag that supports four actions:
- **none**: Take no action.
- **kill**: Kill the container.
- **restart**: Restart the container. Do not combine the `restart`
action with the `--restart` flag. When running inside of
a systemd unit, consider using the `kill` or `stop`
action instead to make use of systemd's restart policy.
- **stop**: Stop the container.
To remain backwards compatible, **none** is the default action.

Support running `podman play kube` in systemd by exploiting the
previously added "service containers". During `play kube`, a service
container is started before all the pods and containers, and is stopped
last. The service container communicates its conmon PID via sdnotify.
Add a new systemd template to dispatch such k8s workloads. The argument
of the template is the path to the k8s file. Note that the path must be
escaped for systemd not to bark:
Let's assume we have a `top.yaml` file in the home directory:
```
$ escaped=$(systemd-escape ~/top.yaml)
$ systemctl --user start podman-play-kube@$escaped.service

Add the notion of a "service container" to play kube. A service
container is started before the pods in play kube and is (reverse)
linked to them. The service container is stopped/removed *after*
all pods it is associated with are stopped/removed.
In other words, a service container tracks the entire life cycle
of a service started via `podman play kube`. This is required to
enable `play kube` in a systemd unit file.
The service container is only used when the `--service-container`
flag is set on the CLI. This flag has been marked as hidden as it
is not meant to be used outside the context of `play kube`. It is
further not supported on the remote client.
The wiring with systemd will be done in a later commit.
