Wrap the given function, taking a kithara message map and producing a confirmation map, to ACK/NACK/REJECT the original message based on keys contained within. :status can have any of the following values:

• :ack
• :nack
• :reject
• :error (an uncaught exception occured)
• :done (do nothing since the message was already explicitly handled)

For :nack, :reject and :error, an additional key :requeue? can be given to indicate whether or not the message should be requeued.

This is a middleware activated by default in the kithara base consumer.
