Create a new template for generating a pod unit file. Eventually, this
allows for treating and extending pod and container generation
seprately.
The `--new` flag now also works on pods.

Refactor the systemd-unit generation code and move all the logic into
`pkg/systemd/generate`. The code was already hard to maintain but I
found it impossible to wire the `--new` logic for pods in all the chaos.
The code refactoring in this commit will make maintaining the code
easier and should make it easier to extend as well. Further changes and
refactorings may still be needed but they will easier.

Rephrase the lookup error when the specified name or ID does not refer
to a container or pod. Until, only the pod-lookup error has been
returned which can be confusing when actually looking for a container;
a user might have just mistyped the ID or name.

Add an `--infra-conmon-pidfile` flag to `podman-pod-create` to write the
infra container's conmon process ID to a specified path. Several
container sub-commands already support `--conmon-pidfile` which is
especially helpful to allow for systemd to access and track the conmon
processes. This allows for easily tracking the conmon process of a
pod's infra container.

Rename the container ID file from "cid" to "ctr-id" to make the
generated unit files a) easier to read and to b) pro-actively
avoid any confusion when pod ID files are being added in the
future.

Allow containers to join an existing pod via the `--pod-id-file` which
is already supported by a number of `podman-pod` subcommands. Also add
tests to make sure it's working and to prevent future regressions.

Support the `--pod-id-file` flag in the rm, start and stop pod commands.
This completes the already support flag in pod-create and is another
prerequisite for generating generic systemd unit files for pods.
Also add completions, docs and tests.

Add a `CreateCommand` field to the pod config which includes the entire
`os.Args` at pod-creation. Similar to the already existing field in a
container config, we need this information to properly generate generic
systemd unit files for pods. It's a prerequisite to support the `--new`
flag for pods.
Also add the `CreateCommand` to the pod-inspect data, which can come in
handy for debugging, general inspection and certainly for the tests that
are added along with the other changes.

Two areas needed tweaking to accomplish this: port parsing and
binding ports on the host.
Parsing is an obvious problem - we have to accomodate an IPv6
address enclosed by [] as well as a normal IPv4 address. It was
slightly complicated by the fact that we previously just counted
the number of colons in the whole port definition (a thousand
curses on whoever in the IPv6 standard body decided to reuse
colons for address separators), but did not end up being that
bad.
Libpod also (optionally) binds ports on the host to prevent their
reuse by host processes. This code was IPv4 only for TCP, and
bound to both for UDP (which I'm fairly certain is not correct,
and has been adjusted). This just needed protocols adjusted to
read "tcp4"/"tcp6" and "udp4"/"udp6" based on what we wanted to
bind to.

Unless `--since` or `--until` is specified, `podman events` will stream
new events. Clarify this behavior in the `--help` message and man page
to avoid confusion.

This allows the containers/conmon repository to share the same VM
images produced by containers/libpod. Included are several packages
which are downloaded only since they might otherwise interfere with
testing for some repos. This allows stable versions to be at the ready
at testing runtime, avoiding any version updates surprising developers.
Also, re-enable running the VM-image check test which was not working
due to a logic problem in Cirrus-CI configuration. Update the neglected
tests so that they pass on all distros.

podman-remote has not been tested. A principal part of the
problem was #5387 - the YAML I wrote did not have the
intended effect, it did not set TEST_REMOTE_CLIENT=true
and because of my multiple iterations I did not catch this
during testing.
Part 1 of this PR is to fix .cirrus.yml to enable remote tests.
Part 2 -- what I had first noticed and tried to fix -- is that
rootless_test.sh was never running remote because, of course,
envariables are not sent via ssh. I reworked integration_test.sh
and rootless_test.sh to use a command-line decision instead.
Part 3, sigh, is to disable one failing integration test
and *all* system tests, because so many of the latter are
failing. Addressing those failures needs to be done in
subsequent PRs. Issues #6538, #6539, #6540 are filed for
some of the problems I isolated. There will be more.
Also, minor, fixed some stale references to varlink.

This fixes an error in the system tests, which expect that when
you try and kill a nonexistent pod with an incorrect signal, you
receive an error about the signal, not the pod.
At the same time, fix a missing return statement in the bindings,
which could also have caused us grief.

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.
