Add naive support for openstack network config. if no config driver have been found, try to detect that we are running a VM on openstack via the smbios information, use the first iface available and temporary activate dhcp on it, to be able to fetch the necessary informations for cloudinit. While here make the rc script execute after devmatch, some ethernet device might be attached via devmatch and may be needed for cloudinit. Tested on OVHCloud Public Cloud.
