machinectl: split OS field in two; print ip addresses (#4058)
This splits the OS field in two : one for the distribution name and one for the the version id. Dashes are written for missing fields. This also prints ip addresses of known machines. The `--max-addresses` option specifies how much ip addresses we want to see. The default is 1. When more than one address is written for a machine, a `,` follows it. If there are more ips than `--max-addresses`, `...` follows the last address.
