hwinfo, system: use min_column_sizes, cleanup
Allow 'Commands:' and 'Options:' line be longer, e.g.:
'Commands that only show information:' or
'Commands that manipulate with devices:'.
Reworked storage command docs.

- clearly split commands that only show/list devices from commands which
  modify devices.
