use of channel.queue_declare() in reader_example.py forces user to have conf permissions for exchange

[kript]

The line
channel.queue_declare(queue = 'Finish')
registers the queue within the default exchange, if it doesn't already exist.

Suggest changing

    channel.queue_declare(queue='Finish')
    channel.basic_publish(exchange='',
                          routing_key='Finish',
                          body=json.dumps(datadict))

inlsf_log_watch.py
to something like

channel.queue_bind(exchange='LSF',
                   queue=queue_name)
    channel.queue_declare(queue='Finish')
    channel.basic_publish(exchange='LSF',
                          routing_key='Finish',
                          body=json.dumps(datadict))

and likewise in reader_example.py, removing the line
channel.queue_declare(queue = 'Finish')
and changing

    channel.basic_consume(callback,
                          queue='Finish',
                          no_ack=True)

to

channel.queue_bind(exchange='LSF',
                   queue=queue_name)
    channel.basic_consume(callback,
                          queue='Finish',
                          no_ack=True)

Happy with the option, this looks pretty sane and may add more options for later use.
