Option parsing should be more strict and only allow supported options and block all others

When trying to delete a console... I was not sure if it was -d or -D and so i tried -D first, the output I saw is:

[root@stratton01 ~]# makegocons -D c910f3zz01

          '_xcat_clientfqdn' => [
                                  'localhost'
                                ],
          'arg' => [
                     '-D'
                   ],
          '_xcat_authname' => [
                                'root'
                              ],
          '_xcat_clientport' => [

          'cwd' => [

          '_allnodes' => [

          'clienttype' => [
                            'cli'
                          ],
          '_xcat_clienthost' => [
                                  'localhost'
                                ],
          'command' => [
                         'makegocons'
                       ],
          '_xcatpreprocessed' => [
                                   1
                                 ]
        };

c910f3zz01: Created

So seems like some verbose (DEBUG?) data is printed, but the console is "Created"

The correct command is -d

[root@stratton01 ~]# makegocons -d c910f3zz01

Hi, @whowutwut , it seems the -D|--debug means '$::DEBUG' for makegocons, and only used in preprocess_request.

But it seems this piece of code is copy from conserver.pm, maybe we shall add '-D|--debug' in the manpage of makegocons and makeconservercf.
