Send the main PID only once. Previously, `(*Container).start()` and
the conmon handler sent them ~simultaneously and went into a race.

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.

Pulling the K8s pause image seems unnecessarily expensive to me. Let's
use the testgitest_v2s2 one which is under our control and weighs only a
couple of KB.
This cut the execution time in less than half on my machine. Since it's
network bound and I am running on fibre, I expect more significant speed
ups in slower networks.

Squash the --quiet test into another one. The test was more complex
than necessary and can easily be squashed into another one to avoid one
more expensive pull.

Rather than assuming a filesystem path, the API service URI is recorded
in the libpod runtime configuration and then reported as requested.
Note: All schemes other than "unix" are hard-coded to report URI exists.

Instead of using the main module we should vendor the test tools in a
different directory. That way we do not add extra dependencies to the
main module which can be problemetic for packages or other users.
This is already done in buildah so this makes us more consitent.

We can vendor the test dependencies such as go-md2man, git-validation
and goimports. This allows us to always install the same version as
specified in go.mod. Also we do not rely on a network connection for
this.
The advantage with this method is that dependabot will also update the
dependencies for us and we do not have to hardcode versions in the
Makefile.

Add the notion of an "exit policy" to a pod. This policy controls the
behaviour when the last container of pod exits. Initially, there are
two policies:
- "continue" : the pod continues running. This is the default policy
when creating a pod.
- "stop" : stop the pod when the last container exits. This is the
default behaviour for `play kube`.
In order to implement the deferred stop of a pod, add a worker queue to
the libpod runtime. The queue will pick up work items and in this case
helps resolve dead locks that would otherwise occur if we attempted to
stop a pod during container cleanup.
Note that the default restart policy of `play kube` is "Always". Hence,
in order to really solve #13464, the YAML files must set a custom
restart policy; the tests use "OnFailure".

When a container is run in the host network namespace we have to keep
the same resolv.conf content and not use the systemd-resolve detection
logic.
But also make sure we still allow --dns options.

The files /etc/hosts, /etc/hostname and /etc/resolv.conf should always
be owned by the root user in the container. This worked correct for
/etc/hostname and /etc/hosts but not for /etc/resolv.conf.
A container run with --userns keep-id would have the reolv.conf file
owned by the current container user which is wrong.
Consolidate some common code in a new helper function to make the code more
cleaner.

add a new option to completely disable xfs quota usage for a volume.
xfs quota set on a volume, even just for tracking disk usage, can
cause weird errors if the volume is later re-used by a container with
a different quota projid. More specifically, link(2) and rename(2)
might fail with EXDEV if the source file has a projid that is
different from the parent directory.
To prevent such kind of issues, the volume should be created
beforehand with `podman volume create -o o=noquota $ID`
