As described in #17777, the `restart` on-failure action did not behave
correctly when the health check is being run by a transient systemd
unit. It ran just fine when being executed outside such a unit, for
instance, manually or, as done in the system tests, in a scripted
fashion.
There were two issue causing the `restart` on-failure action to
misbehave:
1) The transient systemd units used the default `KillMode=cgroup` which
will nuke all processes in the specific cgroup including the recently
restarted container/conmon once the main `podman healthcheck run`
process exits.
2) Podman attempted to remove the transient systemd unit and timer
during restart. That is perfectly fine when manually restarting the
container but not when the restart itself is being executed inside
such a transient unit. Ultimately, Podman tried to shoot itself in
the foot.
Fix both issues by moving the restart logic in the cleanup process.
Instead of restarting the container, the `healthcheck run` will just
stop the container and the cleanup process will restart the container
once it has turned unhealthy.
Backport of commit 9563415430.

Commit 2f29639bd3 added a UX improvement to cleanup/teardown when
running the specified YAML has failed. However, the teardown happens
unconditionally such that rerunning the same YAML file will teardown the
previously created workload instead of just failing with a name-conflict
error (e.g., "pod already exists"). The regression popped up testing
the Ansible system role with Podman v4.4.0.
For now, do not teardown at all on error to quickly fix this regression
for the upcoming Podman v4.4.1 release. The UX improvement is still
desired but must be conditional and only happen on newly created
resources, which probably requires moving it down to the backend.

After https://github.com/containers/netavark/pull/452 `netavark` is
incharge of deciding `custom_dns_servers` if any so lets honor that and
libpod should not set these manually.
This also ensures docker parity
Podman populates container's `/etc/resolv.conf` with custom DNS servers ( specified via `--dns` or `dns_server` in containers.conf )
even when container is connected to a network where `dns_enabled` is `true`.
Current behavior does not matches with docker, hence following commit ensures that podman only populates custom DNS server when container is not connected to any network where DNS is enabled and for the cases where `dns_enabled` is `true`
the resolution for custom DNS server will happen via ( `aardvark-dns` or `dnsname` ).

July 2022: test was flaking on new VM images. We needed new
images, so I filed #15014 and skipped the test.
January 2023: no attention from anyone, so I'll try bumping up
a dd timeout from 10s to 30s. But in the interim, the test
has broken: it used to expect "Containerfile" in output (this
was deliberately added in #13655)... but #16810 changed that
so Containerfile no longer appears. @flouthoc argues that
this too is deliberate (#17059). Okay, so let's change the
test then. All I care about is not adding more regressions.

Until Podman v4.3, privileged rootfull containers would expose all the
host devices to the container while rootless ones would exclude
`/dev/ptmx` and `/dev/tty*`.
When 5a2405ae1b ("Don't mount /dev/tty* inside privileged containers
running systemd") landed, rootfull containers started excluding all the
`/dev/tty*` devices when the container would be running in systemd
mode, reducing the disparity between rootless and rootfull containers
when running in this mode.
However, this commit regressed some legitimate use cases: exposing
non-virtual-terminal tty devices (modems, arduinos, serial
consoles, ...) to the container, and the regression was addressed in
f4c81b0aa5 ("Only prevent VTs to be mounted inside privileged
systemd containers").
This now calls into question why all tty devices were historically
prevented from being shared to the rootless non-privileged containers.
A look at the podman git history reveals that the code was introduced
as part of ba430bfe5e ("podman v2 remove bloat v2"), and obviously
was copy-pasted from some other code I couldn't find.
In any case, we can easily guess that this check was put for the same
reason 5a2405ae1b was introduced: to prevent breaking the host
environment's consoles. This also means that excluding *all* tty
devices is overbearing, and should instead be limited to just virtual
terminals like we do on the rootfull path.
This is what this commit does, thus making the rootless codepath behave
like the rootfull one when in systemd mode.
This leaves `/dev/ptmx` as the main difference between the two
codepath. Based on the blog post from the then-runC maintainer[1] and
this Red Hat bug[2], I believe that this is intentional and a needed
difference for the rootless path.
