    command_map is a keyname -> 'shell command' dictionary with the commands to
    run. They are all run through /bin/sh, so you need to take care of shell
    escaping yourself. To include stderr output of a command, end it with
    "2>&1".

    Just like root_command_output, this passes the command through pkexec,
    unless the caller is already root.

    This is preferrable to using root_command_output() multiple times, as that
    will ask for the password every time.
