We force the isolate option on new newtworks because that is the docker
behavior. However when we inspect them they should not be displayed to
the caller since they have no idea about it and docker-compose throws an
error because of that.

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

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

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.

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.

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.

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

containers can be configured separately.
Also make sure that the pod's RunRoot is always set.
