Auto updates using the "registry" policy require container to be created
with a fully-qualified image reference. Short names are not supported
due the ambiguity of their source registry. Initially, container
creation errored out for non FQN images but it seems that Podman has
regressed.

According to https://systemd.io/CONTAINER_INTERFACE/, systemd will try take
control over /dev/ttyN if exported, which can cause conflicts with the host's tty
in privileged containers. Thus we will not expose these to privileged containers
in systemd mode, as this is a bad idea according to systemd's maintainers.
Additionally, this commit adds a bats regression test to check that no /dev/ttyN
are present in a privileged container in systemd mode
This fixes https://github.com/containers/podman/issues/15878

Background: in order to add aarch64 tests, we had to add
emergency skips to a lot of failing tests. No attempt was
ever made to understand why they were failing.
Fast forward to today, I filed #15888 just to see if tests
are still failing. Looks like a number of them are fixed.
(Yes, magically). Remove those skips.

Followup to #15673 (--format with newlines). I cobbled up a test
for it, but I was sloppy, so the test had issues that I kept
having to band-aid. This is a cleaner way to handle podman-machine.
...and, another unexpected surprise with podman stats. It
fails under rootless cgroupsv1. We can't sweep it under the
rug via skip_if_ubuntu because tests will then fail on RHEL8.
So, add a similar mechanism for testing podman stats.
...plus a non-surprise, the 'search' test flakes. Try minimizing
that by searching only $IMAGE. If quay.io is down, other tests
will certainly fail.

Three tests were running 'container rm' on 'start'ed containers
that might not yet have exited. Fix. Also, tighten up the
tests themselves, to make even more sure that they test
what they're supposed to test.
Discovered, in CI, that 'podman-remote logs --timestamps'
was unimplemented. Thanks to @Luap99 for the fix to that.

Emit a warning to the user when generating a unit with --new on a
container that was created with a custom --restart policy. As shown
in #15284, a custom --restart policy in that case can lead to issues
on system shutdown where systemd attempts to nuke the unit but Podman
keeps on restarting the container.

Restart the health-check timers instead of starting them. This will

Currently the podman command --format output code uses a mix of
report.Formatter and report.Template.
I patched report.Formatter to correctly handle newlines[1]. Since we
cannot fix this with report.Template we have to migrate all users to
report.Formatter. This ensures consistent behavior for all commands.
This change does not change the output.

The field was already exposed already in the `system df` output
so this just required a bit of plumbing and testing.
As part of this, fix `podman systemd df` volume in-use logic.
Previously, volumes were only considered to be in use if the
container using them was running. This does not match Docker's
behavior, where a volume is considered in use as long as a
container exists that uses the volume, even if said container is
not running.

podman --events-backend file events --stream=false should never hang. The
problem is that our tail library will wait for the file to be created
which makes sense when we do not run with --stream=false. To fix this we
can just always create the file when the logger is initialized. This
would also help to report errors early on in case the file is not
accessible.

Podman adds an Error: to every error message. So starting an error
message with "error" ends up being reported to the user as
Error: error ...
This patch removes the stutter.
Also ioutil.ReadFile errors report the Path, so wrapping the err message
with the path causes a stutter.

Trying to catch the wiley metacopy flake: add a debug
condition to run_podman, in system tests, to log all
instances in which output includes the metacopy warning.
The idea is to detect the very first time it happens,
and see what is triggering it.

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.

--debug should not be a global flag, you can only use this as podman
--debug never podman ps --debug. This matches docker and allows us to
add the shorthand "D" since they now no longer conflict.

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
