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
```

Removing exec sessions is guaranteed to evict them from the DB,
but in the case of a zombie process (or similar) it may error and
block removal of the container. A subsequent run of `podman rm`
would succeed (because the exec sessions have been purged from
the DB), which is potentially confusing to users. So let's just
continue, instead of erroring out, if removing exec sessions
fails.
[NO NEW TESTS NEEDED] I wouldn't want to spawn a zombie in our
test VMs even if I could.

This primarily served to protect us against shutting down the
Libpod runtime while operations (like creating a container) were
happening. However, it was very inconsistently implemented (a lot
of our longer-lived functions, like pulling images, just didn't
implement it at all...) and I'm not sure how much we really care
about this very-specific error case?
Removing it also removes a lot of potential deadlocks, which is
nice.

When removing a container created with a --volumes-from a container
created with a built in volume, we complain if the original container
still exists. Since this is an expected state, we should not complain
about it.

We should not check if the network supports dns when we create a

There is a problem with creating and storing the exit command when the
container was created. It only contains the options the container was
created with but NOT the options the container is started with. One
example would be a CNI network config. If I start a container once, then
change the cni config dir with `--cni-config-dir` ans start it a second
time it will start successfully. However the exit command still contains
the wrong `--cni-config-dir` because it was not updated.
To fix this we do not want to store the exit command at all. Instead we
create it every time the conmon process for the container is startet.
This guarantees us that the container cleanup process is startet with
the correct settings.

Podman 4.0 currently errors when you use network aliases for a network which
has dns disabled. Because the error happens on network setup this can
cause regression for old working containers. The network backend should not
validate this. Instead podman should check this at container create time
and also for network connect.

Make use of the new network interface in libpod.
This commit contains several breaking changes:
- podman network create only outputs the new network name and not file
path.
- podman network ls shows the network driver instead of the cni version
and plugins.
- podman network inspect outputs the new network struct and not the cni
conflist.
- The bindings and libpod api endpoints have been changed to use the new
network structure.
The container network status is stored in a new field in the state. The
status should be received with the new `c.getNetworkStatus`. This will
migrate the old status to the new format. Therefore old containers should
contine to work correctly in all cases even when network connect/
disconnect is used.
New features:
- podman network reload keeps the ip and mac for more than one network.
- podman container restore keeps the ip and mac for more than one
network.
- The network create compat endpoint can now use more than one ipam
config.
The man pages and the swagger doc are updated to reflect the latest
changes.

InfraContainer should go through the same creation process as regular containers. This change was from the cmd level
down, involving new container CLI opts and specgen creating functions. What now happens is that both container and pod
cli options are populated in cmd and used to create a podSpecgen and a containerSpecgen. The process then goes as follows
FillOutSpecGen (infra) -> MapSpec (podOpts -> infraOpts) -> PodCreate -> MakePod -> createPodOptions -> NewPod -> CompleteSpec (infra) -> MakeContainer -> NewContainer -> newContainer -> AddInfra (to pod state)

After #8906, there is a potential race condition in container
removal of running containers with `--rm`. Running containers
must first be stopped, which was changed to unlock the container
to allow commands like `podman ps` to continue to run while
stopping; however, this also means that the cleanup process can
potentially run before we re-lock, and remove the container from
under us, resulting in error messages from `podman rm`. The end
result is unchanged, the container is still cleanly removed, but
the `podman rm` command will seem to have failed.
Work around this by pinging the database after we stop the
container to make sure it still exists. If it doesn't, our job is
done and we can exit cleanly.
