This allows tools like Cockpit to know that the pod in question
has also been updated, so they can refresh the list of containers
in the pod.

We added the concept of image volumes in 2.2.0, to support
inspecting an image from within a container. However, this is a
strictly read-only mount, with no modification allowed.
By contrast, the new `image` volume driver creates a c/storage
container as its underlying storage, so we have a read/write
layer. This, in and of itself, is not especially interesting, but
what it will enable in the future is. If we add a new command to
allow these image volumes to be committed, we can now distribute
volumes - and changes to them - via a standard OCI image registry
(which is rather new and quite exciting).
Future work in this area:
- Add support for `podman volume push` (commit volume changes and
push resulting image to OCI registry).
- Add support for `podman volume pull` (currently, we require
that the image a volume is created from be already pulled; it
would be simpler if we had a dedicated command that did the
pull and made a volume from it)
- Add support for scratch images (make an empty image on demand
to use as the base of the volume)
- Add UOR support to `podman volume push` and
`podman volume pull` to enable both with non-image volume
drivers

This reverts commit c20abf12c7. In the
absence of `ExecStop` step, systemd will send the stop/kill signals to
the main PID while I asummed that systemd would jump directly to an
ExecStopPost step instead.
Hence revert the commit to let Podman take care of stopping rather than
systemd.

Drop the ExecStop step to simplify the generated units a bit.
The extra ExecStopPost step was added by commit e5c3432944. If the
main PID (i.e., conmon) is killed, systemd will not execute ExecStop
(since the main PID is already down) but only execute the *Post steps.
Credits to the late Ulrich Obergfell for tracking this issue down; he is
missed.
The ExecStop step can safely be dropped since the Post step will take of
stopping (and removing) in any case.

Originally, during pod removal, we locked every container in the
pod at once, did a number of validity checks to ensure everything
was safe, and then removed all the containers in the pod.
A deadlock was recently discovered with this approach. In brief,
we cannot lock the entire pod (or much more than a single
container at a time) without causing a deadlock. As such, we
converted to an approach where we just looped over each container
in the pod, removing them individually. Unfortunately, this
removed a lot of the validity checking of the earlier approach,
allowing for a lot of unintended bad things. Infra containers
could be removed while containers in the pod still depended on
them, for example.
There's no easy way to do validity checks while in a simple loop,
so I implemented a version of our graph-traversal logic that
currently handles pod start. This version acts in the reverse
order of startup: startup starts from containers which depend on
nothing and moves outwards, while removal acts on containers which
have nothing depend on them and moves inwards. By doing graph
traversal, we can guarantee that nothing is removed while
something that depends on it still exists - so the infra
container should be the last thing in a pod that is removed, for
example.
In the (unlikely) case that a graph of the pod's containers
cannot be built (most likely impossible without database editing)
the old method of pod removal has been retained to ensure that
even misbehaving pods can be forcibly evicted from the state.
I'm fairly confident that this resolves the problem, but there
are a lot of assumptions around dependency structure built into
the original pod removal code and I am not 100% sure I have
captured all of them.

When creating a new pod without the `--name` flag, e.g.:
`podman pod create foobar`
it will get the name `foobar` implicitly and this will be recorded as the in the
`podCreateArgs`. Unfortunately, the implicit name only works if it appears as
the **last** argument of the startup command.
With 6e2e3a78ed we started appending the pod
security policy to the startCommand, resulting in the following `ExecStartPre=`
line:
```
/usr/bin/podman pod create --infra-conmon-pidfile %t/pod-foobar.pid --pod-id-file %t/pod-foobar.pod-id foobar --exit-policy=stop
```
This fails to launch, as the `pod create` command expects only a single
non-flag parameter, but it assumes that `exit-policy=stop` is a second and
terminates immediately instead.

Change the dependencies from a pod unit to its associated container
units from `Requires` to `Wants` to prevent the entire pod from
transitioning to a failed state. Restart policies for individual
containers can be configured separately.
Also make sure that the pod's RunRoot is always set.

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, we can add a new test for the
newline bug when the common PR is vendored in.
Also fixa bug since the table format is expected to print headers as
well.

`--cpu-rt-period` and `--cpu-rt-runtime` options are only

Therefore, podman prints an warning message and ignores these

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.

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.
