In order to run Podman with VM-based runtimes unprivileged, the
network must be set up prior to the container creation. Therefore
this commit modifies Podman to run rootless containers by:
1. create a network namespace
2. pass the netns persistent mount path to the slirp4netns
to create the tap inferface
3. pass the netns path to the OCI spec, so the runtime can
enter the netns
Closes#2897

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.

There are two cases logdriver can be empty, if it wasn't set by libpod, or if the user did --log-driver ""
The latter case is an odd one, and the former is very possible and already handled for LogPath.
Instead of printing an error for an entirely reasonable codepath, let's supress the error
