minor correction to logging statement
Spawn and Minion will not attempt to retry connections to rabbitmq.   this is not final code but is functional so I want to checkpoint.
Gracefully handle disruptions to the rabbitmq message broker.  Both spawn and minion will attempt to reconnect and then resume processing once the connection has been re-established.
