Containers have the ability to add Linux system capabilities to them, this is
done using the "set container name <name> cap-add" command.
The CLI node sounds off and rather should be "set container name <name>
capability" instead as we use and pass a capability to a container and not
add/invent new ones.

The script's name is always provided as the first argument sys.argv[0]
Expected length for argv is 2 (script itself + config file)
Change: 'if (len(argv) < 1)' to 'if len(argv) < 2'

Commit 60c80df4 ("container: T4870: bump package version 0 -> 1 for filesystem
change") introduced a fundamental change in the container storage driver that
required a manual migration step from the user to not loose any data.
This commit removes the manual user interaction and temporary exports the
container images and re-imports them after the filesystem got changed. The only
things that get lost are orphaned container images no longer referenced by the
CLI - thats an adequate trade-off as those images can always be re-added to the
system.

move from vfs to overlay driver
The following pre iage upgrade script must be executed to have containers after
the reboot:
for pod in $(cli-shell-api listActiveNodes container name); do
systemctl stop vyos-container-${pod//\'}.service
done
sed -i 's/vfs/overlay/g' /etc/containers/storage.conf /usr/share/vyos/templates/container/storage.conf.j2
rm -rf /usr/lib/live/mount/persistence/container/storage/libpod
for pod in $(cli-shell-api listActiveNodes container name); do
image=$(cli-shell-api returnActiveValue container name ${pod//\'} image)
podman image pull $image
systemctl start vyos-container-${pod//\'}.service
done
for dir in vfs vfs-containers vfs-images vfs-layers; do
rm -rf /usr/lib/live/mount/persistence/container/storage/$dir
done
