Add service and helper script for static network configuration
After interface renaming is done, perform the following actions: - Configure each interface for which we have a configuration file - Configuration file contains lines that we pass directly to iproute2 - Configure static routing in a similar fashion - Set the configured interfaces up Signed-off-by: David Oberhollenzer <david.oberhollenzer@tele2.at>
