Several podman commands accept no subcommands. Some
of those were not actually checking, though, which
could lead to user confusion. Added validation where
missing; and, refactored to minimize duplication.
(Side note: I decided against using cobra.NoArgs
because its error message, "unknown command",
misleadingly implies that there are known ones).
Also added validation to varlink

* ps now on main command
* sign is no longer on main commmand
* ls, list no longer are valid main aliases for images
* ls, list does work for podman image

We had a regression on master where we broke the build for
non-Varlink builds. Catch this in CI in the future.

The commands checkpoint and restore should only be available under
'podman container'. This is probably a result of the recent cobra
migration.

Conceptually simple: include, where applicable, a brief
description of command-line options for each subcommand.

No reason to do it in util/ anymore. It's always going to be a
subdirectory of c/storage graph root by default, so we can just
set it after the return.

There are some cases where we might not be properly adjusting the
volume path after setting the storage graph root. Ensure that we
always set volume path to be a child of graph root.

This release updates buildah to use containers/image v1.5
Which fixes a crash issue when pulling container images.

Instead of passing in defaults via WithStorageConfig after
computing them in cmd/podman/libpodruntime, do all defaults in
libpod itself.
This can alleviate ordering issues which caused settings in the
libpod config (most notably, volume path) to be ignored.

if there is already a bind mount specified for the target, do not
create a new volume.

When removing volumes with rm --volumes we want to only remove
volumes that were created with the container. Volumes created
separately via 'podman volume create' should not be removed.
Also ensure that --rm implies volumes will be removed.

when using the play kube command, we need to make sure that containers
with dependancies are started in proper order. in this case, the infra
container must be started first.

If this doesn't match, we end up not being able to access named
volumes mounted into containers, which is bad. Use the same
validation that we use for other critical paths to ensure this
one also matches.
Signed-off-by: Matthew Heon <matthew.heon@pm.me>
We want named volumes to be created in a subdirectory of the
c/storage graph root, the same as the libpod root directory is
now. As such, we need to adjust its location when the graph root
changes location.
Also, make a change to how we set the default. There's no need to
explicitly set it every time we initialize via an option - that
might conflict with WithStorageConfig setting it based on graph
root changes. Instead, just initialize it in the default config
like our other settings.

Based on user feedback, refine the "Out of scope" section regarding
`docker-compose`:
* Explain why Podman uses Kubernetes YAML.
* Explain how `podman-play-kube` and `podman-generate-kube` fit into the
picture.

CRIU creates a log file during checkpointing in .../userdata/dump.log.
The problem with this file is, is that CRIU injects a parasite code into
the container processes and this parasite code also writes to the same
log file. At this point a process from the inside of the container is
trying to access the log file on the outside of the container and
SELinux prohibits this. To enable writing to the log file from the
injected parasite code, this commit creates an empty log file and labels
the log file with c.MountLabel(). CRIU uses existing files when writing
it logs so the log file label persists and now, with the correct label,
SELinux no longer blocks access to the log file.
