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.

kube: plug HostUsers in the pod spec

map HostUsers=false to userns=auto.
One difference with the current implementation in the Kubelet is that
the podman default size is 1024 while the Kubelet uses 65536.
This is done on purpose, because 65536 is a problem for rootless as
the entire IDs space would be allocated to a single pod.

`--cpu-rt-period` and `--cpu-rt-runtime` options are only
supported on cgroups V1 rootful systems.
Therefore, podman prints an warning message and ignores these
options when we use cgroups V2 systems.

fix podman pod inspect to support multiple pods

Just like the other inspect commands `podman pod inspect p1 p2` should
return the json for both.
To correctly implement this we follow the container inspect logic, this
allows use to reuse the global inspect command.
Note: To not break the existing single pod output format for podman pod
inspect I added a pod-legacy inspect type. This is only used to make
sure we will print the pod as single json and not an array like for the
other commands. We cannot use the pod type since podman inspect --type
pod did return an array and we should not break that as well.

This avoids setting values in the spec which are not supported on
FreeBSD - including these values causes warning messages for the
unsupported features.

Add auto-update support to `podman kube play`. Auto-update policies can
be configured for:
* the entire pod via the `io.containers.autoupdate` annotation
* a specific container via the `io.containers.autoupdate/$name` annotation
To make use of rollbacks, the `io.containers.sdnotify` policy should be
set to `container` such that the workload running _inside_ the container
can send the READY message via the NOTIFY_SOCKET once ready. For
further details on auto updates and rollbacks, please refer to the
specific article [1].
Since auto updates and rollbacks bases on Podman's systemd integration,
the k8s YAML must be executed in the `podman-kube@` systemd template.
For further details on how to run k8s YAML in systemd via Podman, please
refer to the specific article [2].
An examplary k8s YAML may look as follows:
```YAML
apiVersion: v1
kind: Pod
metadata:
annotations:
io.containers.autoupdate: "local"
io.containers.autoupdate/b: "registry"
labels:
app: test
name: test_pod
spec:
containers:
- command:
- top
image: alpine
name: a
- command:
- top
image: alpine
name: b

Almost all of SpecGenToOCI deals with linux-specific aspects of the
runtime spec. Rather than try to factor this out piecemeal, I think it
is cleaner to move the whole function along with its implementation
helper functions. This also meams we don't need non-linux stubs for
functions called from oci_linux.go

When a kube yaml has a volume set as empty dir, podman
will create an anonymous volume with the empty dir name and
attach it to the containers running in the pod. When the pod
is removed, the empy dir volume created is also removed.
