shared/shell: Add non-interactive mode
This detects if any command was given as parameter, execute it and
exit disabling all other outputs:
bluetoothctl list
Controller 00:1B:DC:07:31:88 Vudentz's T460s #1 [default]
Controller B8:8A:60:D8:17:D7 BlueZ-1
It is also possible to run interactive command with use of timeout
option:
bluetoothctl --timeout=10 advertise on
