When an image config sets config.User [1] to a numeric group (like
1000:1000), but those values do not exist in the container's
/etc/group, libpod is currently breaking:
$ podman run --rm registry.svc.ci.openshift.org/ci-op-zvml7cd6/pipeline:installer --help
error creating temporary passwd file for container 228f6e9943d6f18b93c19644e9b619ec4d459a3e0eb31680e064eeedf6473678: unable to get gid 1000 from group file: no matching entries in group file
However, the OCI spec requires converters to copy numeric uid and gid
to the runtime config verbatim [2].
With this commit, I'm frontloading the "is groupspec an integer?"
check and only bothering with lookup.GetGroup when it was not.
I've also removed a few .Mounted checks, which are originally from
00d38cb3 (podman create/run need to load information from the image,
2017-12-18, #110). We don't need a mounted container filesystem to
translate integers. And when the lookup code needs to fall back to
the mounted root to translate names, it can handle erroring out
internally (and looking it over, it seems to do that already).

when a user specifies --pod to podman create|run, we should create that pod
automatically. the port bindings from the container are then inherited by
the infra container. this signicantly improves the workflow of running
containers inside pods with podman. the user is still encouraged to use
podman pod create to have more granular control of the pod create options.

like containers and images, users would benefit from being able to check
if a pod exists in local storage. if the pod exists, the return code is 0.
if the pod does not exists, the return code is 1. Any other return code
indicates a real errors, such as permissions or runtime.

it was reported on IRC that Podman on Ubuntu failed as
newuidmap/newgidmap were not installed by default.
Raise an error if we are not allowing single mappings (used only by
the tests suite) and any of the binaries is not present.

podman logs already supports the latest command line switch. users should be able
to use the short-options combined (i.e. podman logs -lf).

we need to inherit this change from runc.
commit 869add33186caff4a22e3e11a7472a2d48d77889:
rootless: fix running with /proc/self/setgroups set to deny
This is a regression from 06f789cf26774dd64cb2a9cc0b3c6a6ff832733b
when the user namespace was configured without a privileged helper.
To allow a single mapping in an user namespace, it is necessary to set
/proc/self/setgroups to "deny".
For a simple reproducer, the user namespace can be created with
"unshare -r".

Currently we are mounting /dev/shm from disk, it should be from a tmpfs.
User Namespace supports tmpfs mounts for nonroot users, so this section of
code should work fine in bother root and rootless mode.

Don't try to argparse command-line arguments on the right-hand
side of the image; those are intended for the container command:
pypodman create fedora ls -l
pypodman run fedora find / -name foo
pypodman run fedora bash -c 'echo hi'
If/when `pypodman exec` gets implemented, it should use this too.

Whe running unittests on newer golang versions, we observe failures with some
formatting types when no declared correctly.
