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
