I thought about declaring the exchange in the producer, but again that
would be only an instantiation check. Since the class instance is long
lasting, it's not something I would want to do with every
basic_publish, so if by some method the exchange were to disappear
after object instantiation, the app still wouldn't know until the
object (and app) were torn down.
