*multipathd* now supports raw format mode in *multipathd* formatted output commands
The *multipathd* formatted output commands now offer `raw` format mode, which removes the headers and additional padding between fields. Support for additional format wildcards has been added as well. Raw format mode makes it easier to collect and parse information about multipath devices, particularly for use in scripting.
