This came out of a conversation with Valentin about
systemd-managed Podman. He discovered that unit files did not
properly handle cases where Conmon was dead - the ExecStopPost
`podman rm --force` line was not actually removing the container,
but interestingly, adding a `podman cleanup --rm` line would
remove it. Both of these commands do the same thing (minus the
`podman cleanup --rm` command not force-removing running
containers).
Without a running Conmon instance, the container process is still
running (assuming you killed Conmon with SIGKILL and it had no
chance to kill the container it managed), but you can still kill
the container itself with `podman stop` - Conmon is not involved,
only the OCI Runtime. (`podman rm --force` and `podman stop` use
the same code to kill the container). The problem comes when we
want to get the container's exit code - we expect Conmon to make
us an exit file, which it's obviously not going to do, being
dead. The first `podman rm` would fail because of this, but
importantly, it would (after failing to retrieve the exit code
correctly) set container status to Exited, so that the second
`podman cleanup` process would succeed.
To make sure the first `podman rm --force` succeeds, we need to
catch the case where Conmon is already dead, and instead of
waiting for an exit file that will never come, immediately set
the Stopped state and remove an error that can be caught and
handled.

We experienced regression when using the latest `v1.2.0-dev` bats in
Ubuntu 20.04 (see github.com/containers/libpod/pull/6418). Using
bats v1.1.0 worked in the Ubuntu test VM.

This is the other command that benefits greatly from being run in
parallel, due to the potential 15-second timeout for containers
that ignore SIGTERM.
While we're at it, also clean up how stop timeout is set. This
needs to be an optional parameter, so that the value set when the
container is created with `--stop-timeout` will be respected.

Systemd enablement has to happen on the server side, since we need
check if the image is running systemd.
Also need to make sure user setting the StopSignal is not overriden on the
server side. But if not set and using systemd, we set it correctly.

This code will run container operations in parallel, up to a
given maximum number of threads. Currently, it has only been
enabled for local `podman rm` as a proof of concept.

We were picking up defaults from the client's containers.conf,
which broke pod namespaces. The server-side code already checks
containers.conf when not explicitly overridden by the user, or by
the container being part of a pod (the last bit being our bug).
This only manifested on systems with a containers.conf installed,
so RHEL 8 and Fedora 32 (which means our F32 CI VMs likely should
have caught it, but didn't, which is concerning).
This prevents defaults for these flags being shown, but they were
incorrect anyways for `podman-remote`, so I'm not terribly
concerned.

When we moved to the new Namespace types in Specgen, we made a
distinction between taking a namespace from a pod, and taking it
from another container. Due to this new distinction, some code
that previously worked for both `--pod=$ID` and
`--uts=container:$ID` has accidentally become conditional on only
the latter case. This happened for Hostname - we weren't properly
setting it in cases where the container joined a pod.
Fortunately, this is an easy fix once we know to check the
condition.
Also, ensure that `podman pod inspect` actually prints hostname.

- (minor): apiv2 tests: check for full ID
Observation made while reviewing #6461: tests were checking
only for a 12-character container/image ID in return value.
It's actually 64, and we should test for that. This should
also minimize confusion in a future maintainer.
- podman pause/unpause: new test
Runs a 'date/sleep' loop, pauses container, sleeps 3s,
restarts, then confirms that there's a 3- to 6-second
gap in the logs for the container.
- podman healthcheck: new test
run a container with healthcheck, test both healthy
and unhealthy conditions
- podman pod: check '{{.Pod}}' field in podman ps
Hey, as long as we have a pod with two running
containers, might as well confirm that 'podman ps'
returns the expected pod ID.
