When playing a kube YAML file, it can be desirable to be able to build

Depending how the user logs in to the root account, XDG_RUNTIME_DIR is
set to /run/user/0 or it is unset. For conmon we already set it always
to an empty string. The inconsistency is causing issues for the dnsname
plugin. To fix it unset XDG_RUNTIME_DIR for the podman process.

Add support for simple rollbacks during `podman auto-update`. Rollbacks
are enabled by default. If a systemd unit cannot be restarted after an
update, the previous image will be retagged and the unit will be
restarted a second time.
Add system tests for rollbacks. Also fix a bug in the restart sequence;
we have to use the channel to actually know whether the restart was
successful or not.
NOTE: To make rollbacks really useful, users must run their containers
with `--sdnotify=container` such that the containers send the ready
message over the (mounted) socket. This way, restarting the systemd
units during auto update will block until the message has been received
(or a timeout kicked in).

this is the first pass at implementing init containers for podman pods.
init containersare made popular by k8s as a way to run setup for pods
before the pods standard containers run.
unlike k8s, we support two styles of init containers: always and
oneshot. always means the container stays in the pod and starts
whenever a pod is started. this does not apply to pods restarting.
oneshot means the container runs onetime when the pod starts and then is
removed.

This adds support to checkpoint containers out of pods and restore
container into pods.
It is only possible to restore a container into a pod if it has been
checkpointed out of pod. It is also not possible to restore a non pod
container into a pod.
The main reason this does not work is the PID namespace. If a non pod
container is being restored in a pod with a shared PID namespace, at
least one process in the restored container uses PID 1 which is already
in use by the infrastructure container. If someone tries to restore
container from a pod with a shared PID namespace without a shared PID
namespace it will also fail because the resulting PID namespace will not
have a PID 1.

podman stats polled by default in a 1 sec period.
This can put quite some load on a machine if you run many containers.
The default value is now 5 seconds.
You can change this interval with a new, optional, --interval, -i cli flag.
The api request got also a interval query parameter for the same purpose.
Additionally a unused const was removed.
Api and cli will fail the request if a 0 or negative value is passed in.
