Subject: Implement shortcut 'ip=<ifname>:static' for static configuration
To simplify static configurate we should be pulling in the
existing 'ifcfg' files when running in hostonly mode.
With that we can implement the shortcut 'ip=<ifname>:static'
to use the existing configuration from the ifcfg file.
