Subject: Update cli_printMessage.sh:


    - Remove the verification about "first argument required". There
      is no specific order when retriving non-option arguments from
      the positional parameters because we are using getopt to retrive
      them.

    - On the `--as-response-line' option, do not use
      `cli_printMessage' to print the message line. Here, the message
      string contains the character `-' which is used by getopt to
      identify option arguments. Using any `-' sign in the message
      itself may confuse getopt or provoke centos-art.sh to report an
      error.  This is a limitation we are facing right now. 
      
      It is not possible to use `-' in the message side because the
      whole ARGUMENT string is passed to getopt and we cannot escape
      them either (as we did with the apostrophe character) because
      that would escape real options too and would suppress the whole
      idea of using getopt.

      To workaround this issue, use `echo' command instead of
      cli_printMessage to print `--as-response-line' messages and
      redirect the `echo' output to the standard error output.
