Add a new field `ExitCodePropagation` field to allow for configuring the

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.

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.

Enable the --configmap flag for the remote case of podman
kube play. Users can pass in the paths to the configmap files
for kube play to use when creating the pods and containers from
a kube yaml file. The configmap file is read and the contents are
appended to the contents of the main yaml file before passed to the
remote client.

gvproxy listens on 127.0.0.1, using localhost as hostname can result in
the client trying to connect to the ipv6 localhost (`::1`). This will
fail as shown in the issue. This switches the hostname in the system
connection to 127.0.0.1 to fix this problem.
I switched the qemu, hyperV and WSL backend. I haven't touched the
applehv code because it uses two different ips and I am not sure what is
the correct thing there. I leave this to Brent to figure out.

These annotations can have security implications - crun, for
example, allows rootless containers to preserve the user's groups
through an annotation. We absolutely should not include
annotations from an untrusted image off the internet by default.
We may consider whitelisting some annotations (e.g. the legacy
WASM annotations), but given that there is now a more explicit
way of specifying an image uses the WASM runtime in the OCI image
spec, I'm just tearing this out entirely for now.

In rootFsSize(), instead of calculating the size of the diff for every
layer of the container's base image, ask the storage library for the sum
of the values it recorded when it first wrote those layers.
In a similar fashion, teach rwSize() to use the library's
ContainerSize() method instead of trying to roll its own.
Replace calls to pkg/util.SizeOfPath() with calls to
github.com/containers/storage/pkg/directory.Size(), which does the same
thing.

The logic which checks for duplicated volumes here did not work
correctly because it used filepath.Clean(). However the writes to the
volDestinations map did not thus the string no longer matched when you
included a final slash for example.
So we can either call Clean() on all or no paths. I decided to call it
on no path because this is what we do right now. Just the check did it.

The remote API will wait 300s by default before conmon will call the
cleanup. In the meantime when you inspect an exec session started with
ExecStart() (so not attached) and it did exit we do not know that. If
a caller inspects it they think it is still running. To prevent this we
should sync the session based on the exec pid and update the state
accordingly.
For a reproducer see the test in this commit or the issue.

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).
