We have had some issues with users squashing large images or pulling large
content from github, that could trigger crashes based on the size of /tmp.
Docker had an issue with this back in 2016. https://github.com/golang/go/issues/14021
The discussion there was to change the default to /var/tmp.
This change will only effect systems that do not set the TMPDIR environment variable.

detect if the current user namespace doesn't match the configuration
in the /etc/subuid and /etc/subgid files.
If there is a mismatch, raise a warning and suggest the user to
recreate the user namespace with "system migrate", that also restarts
the containers.

prune unwanted messages when running a container remotely. also, cp is
not remote-enabled yet and as such should not be available on the remote
client.

Support generating systemd unit files for a pod. Podman generates one
unit file for the pod including the PID file for the infra container's
conmon process and one unit file for each container (excluding the infra
container).
Note that this change implies refactorings in the `pkg/systemdgen` API.

Add the digestfile option to the push command so the digest can
be stored away in a file when requested by the user. Also have added
a debug statement to show the completion of the push.

Drop the support for remote clients to generate systemd-service files.
The generated files are machine-dependent and hence relate only to the
a local machine. Furthermore, a proper service management when using
a remote-client is not possible as systemd has no access to a process.
Dropping the support will also reduce the risk of making users believe
that the generated services are usable in a remote scenario.

subcommand displays a summary of the cni networks ala ps. and the rm

Requirement from https://github.com/containers/libpod/issues/3575#issuecomment-512238393
Added --pull for podman create and pull to match the newly added flag in docker CLI.
`missing`: default value, podman will pull the image if it does not exist in the local.
`always`: podman will always pull the image.
`never`: podman will never pull the image.

Previously, we use CreateConfig's Command to populate container
Command (which is used as CMD for Inspect and Commit).
Unfortunately, CreateConfig's Command is the container's full
command, including a prepend of Entrypoint - so we duplicate
Entrypoint for images that include it.
Maintain a separate UserCommand in CreateConfig that does not
include the entrypoint, and use that instead.

Begin to separate the internal structures and frontend for
inspect on volumes. We can't rely on keeping internal data
structures for external presentation - separating presentation
and internal data format is good practice.
