We initially believed that implementing this required support for
restarting containers after reboot, but this is not the case.
The unless-stopped restart policy acts identically to the always
restart policy except in cases related to reboot (which we do not
support yet), but it does not require that support for us to
implement it.
Changes themselves are quite simple, we need a new restart policy
constant, we need to remove existing checks that block creation
of containers when unless-stopped was used, and we need to update
the manpages.

Test has been flaking excessively. A quick look shows that
the test itself is broken, making a bad assumption.
'podman logs -f' is guaranteed to exit when a container
terminates. This does not (and should not) mean that the
container has been cleaned up. It is undefined and unsafe
to run 'podman run -n same-name-as-terminated-container'
immediately after 'podman logs' exits.
Solution: instead of 'podman run', do 'podman inspect'.
This, too, is unsafe, but we can expect to see one of
two possible conditions:
1) command succeeds, in which case we require that
container State.Status be "exited"; or
2) command fails, in which case we expect "no such
container" in error output
For full coverage we should add a small delay-check test
to (1) to ensure that the container is cleaned up after
a short amount of time. Leaving that as a TODO because
it's more than my Go skills can handle, and I want to
get this checked in ASAP to get rid of the flake hassle.

This started as a small fix to `podman inspect` where a container
and image, with the same name/tag, were present, and
`podman inspect` was run on that name. `podman inspect` in 1.9
(and `docker inspect`) will give you the container; in v2.0, we
gave the image. This was an easy fix (just reorder how we check
for image/container).
Unfortunately, in the process of testing this fix, I determined
that we regressed in a different area. When you run inspect on
a number of containers, some of which do not exist,
`podman inspect` should return an array of inspect results for
the objects that exist, then print a number of errors, one for
each object that could not be found. We were bailing after the
first error, and not printing output for the containers that
succeeded. (For reference, this applied to images as well). This
required a much more substantial set of changes to properly
handle - signatures for the inspect functions in ContainerEngine
and ImageEngine, plus the implementations of these interfaces,
plus the actual inspect frontend code needed to be adjusted to
use this.

Add a `--replace` flag to the `pod create` command. If another pod with
the same name already exists, it will be replaced and removed.
Adding this flag is motivated by #5485 to make running Podman in systemd
units (or any other scripts/automation) more robust. In case of a
crash, a pod may not be removed by a sytemd unit anymore. The
`--replace` flag allows for supporting crashes.
Note that the `--replace` flag does not require the `--name` flag to be
set, so it can be set unconditionally in `podman generate systemd`.

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.

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.

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.

- (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.

We are currently able to inspect images with
`podman container inspect` and containers with
`podman image inspect` and neither of those seem correct. This
ensures that the appropriate flags, and only the appropriate
flags, are available for each specialized exec, and they can only
inspect the specific type they were intended to.
