the "pod ps" command first retrieves the list of all pods, then
iterates over the list to inspect each pod. This introduce a race
since a pod could be deleted in the meanwhile by another process.
Solve it by ignoring the define.ErrNoSuchPod error.

currently, setting any sort of resource limit in a pod does nothing. With the newly refactored creation process in c/common, podman ca now set resources at a pod level
meaning that resource related flags can now be exposed to podman pod create.
cgroupfs and systemd are both supported with varying completion. cgroupfs is a much simpler process and one that is virtually complete for all resource types, the flags now just need to be added. systemd on the other hand
has to be handeled via the dbus api meaning that the limits need to be passed as recognized properties to systemd. The properties added so far are the ones that podman pod create supports as well as `cpuset-mems` as this will
be the next flag I work on.

I am constantly attempting to add the podname to the last
argument to podman pod create. Allowing this makes it match
podman volume create and podman network create.
It does not match podman container create, since podman container create
arguments specify the arguments to run with the container.
Still need to support the --name option for backwards compatibility.

Add the notion of a "service container" to play kube. A service
container is started before the pods in play kube and is (reverse)
linked to them. The service container is stopped/removed *after*
all pods it is associated with are stopped/removed.
In other words, a service container tracks the entire life cycle
of a service started via `podman play kube`. This is required to
enable `play kube` in a systemd unit file.
The service container is only used when the `--service-container`
flag is set on the CLI. This flag has been marked as hidden as it
is not meant to be used outside the context of `play kube`. It is
further not supported on the remote client.
The wiring with systemd will be done in a later commit.

Add the notion of an "exit policy" to a pod. This policy controls the
behaviour when the last container of pod exits. Initially, there are
two policies:
- "continue" : the pod continues running. This is the default policy
when creating a pod.
- "stop" : stop the pod when the last container exits. This is the
default behaviour for `play kube`.
In order to implement the deferred stop of a pod, add a worker queue to
the libpod runtime. The queue will pick up work items and in this case
helps resolve dead locks that would otherwise occur if we attempted to
stop a pod during container cleanup.
Note that the default restart policy of `play kube` is "Always". Hence,
in order to really solve #13464, the YAML files must set a custom
restart policy; the tests use "OnFailure".

Use the new logic from c/common to create the hosts file. This will help
to better allign the hosts files between buildah and podman.
Also this fixes several bugs:
- remove host entries when container is stopped and has a netNsCtr
- add entries for containers in a pod
- do not duplicate entries in the hosts file
- use the correct slirp ip when an userns is used
Features:
- configure host.containers.internal entry in containers.conf
- configure base hosts file in containers.conf

system tests: add assert(), and start using it

Problem: the system test 'is()' checker was poorly thought out.
For example, there is no way to check for inequality or for
absence of a substring.
Solution, step 1: introduce new assert(), copied almost verbatim
from buildah, where it has been successful in addressing the
gaps in is().
The logical next step is to search the tests for 'die' and
for 'run', looking for negative assertions which we can
replace with assert(). There were a lot, and in the process
I found a number of ugly bugs in the tests themselves. I've
taken the liberty of fixing these.
Important note: at this time we have both assert() and is().
Replacing all instances of is() would be impossible to review.

It seems this breaks older version of `podman-remote` users hence it
looks like this patch would be a better candidate for podman `5.0`

runs successfully
* test multiple --net options (regression #8057)
- images, run, build, exec tests: add multiple-flag

whether options are overridden or accumulated.
- ps test : add --filter and --sort tests
- pod test: run 'ping' inside container (confirms that
container gets PING capability)

- run --userns=keep-id: confirm that $HOME gets set (#8013)
- inspect: confirm that JSON output is a sane number of
lines (10 or more), not an unreadable one-liner (#8011
and #8021). Do so with image, pod, network, volume
because the code paths might be different.
- cgroups: confirm that 'run' preserves cgroup manager (#7970)
- sdnotify: reenable tests, and hope CI doesn't hang. This
test was disabled on August 18 because CI jobs were hanging
and timing out. My suspicion was that it was #7316, which
in turn seems to have hinged on conmon #182. The latter
was merged on Sep 16, so let's cross our fingers and see
what happens.
Also: remove inaccurate warning from a networking test.

info, images, run, networking tests: remove some skip_if_remote()s
that were added in the varlink days. All of these tests now seem
to work with APIv2.
help test: check that first output line from 'podman --help'
is the program description (regression check for #7273).
load test: clean up stray images, rewrite test to make it conform
to existing convention. In the process, discover and file #7337
exec test (and networking): file #7360, and add FIXME comment
to skip()s suggesting evaluating those tests once that is fixed.
pod test: now that #6328 is fixed, use 'podman pod inspect --format'
instead of relying on jq
Various other tests: add an explanation of why test is disabled
so we can more easily distinguish "this will never be meaningful
under remote" vs "hey, doesn't work for now, but maybe someday".

podman-remote is in better shape now. Let's see what needs
to be done to reenable remote system tests.
- logs test: skip multilog, it doesn't work remote
- diff test: use -l only when local, not with remote
- many other tests: skip_if_remote, with 'FIXME: pending #xxxx'
where xxxx is a filed issue.
Unrelated: added new helper to skip_if_remote and _if_rootless,
where we check if the source message includes "remote"/"rootless"
and insert it if missing. This is a minor usability enhancement
to make it easier to understand at-a-glance why a skip triggers.

- (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.
