when running in rootless mode and using systemd as cgroup manager
create automatically a systemd scope when the user doesn't own the
current cgroup.
This solves a couple of issues:
on cgroup v2 it is necessary that a process before it can moved to a
different cgroup tree must be in a directory owned by the unprivileged
user. This is not always true, e.g. when creating a session with su
-l.
Closes: https://github.com/containers/libpod/issues/3937
Also, for running systemd in a container it was before necessary to
specify "systemd-run --scope --user podman ...", now this is done
automatically as part of this PR.

This is mostly used with Systemd, which really wants to manage
CGroups itself when managing containers via unit file.

This isn't included in Docker, but seems handy enough.
Use the new API for 'volume rm' and 'volume inspect'.

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.

Use a consistent format for description of the <size><unit> flags.
Also, avoid backticks for /dev/shm, as that's interpreted as the format
by the flag parsing lib.

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.

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.
