Wrap the given function, taking a kithara message map, making sure it returns a kithara confirmation map to be processed by wrap-confirmation.

• :default-confirmation will be used if the result is not a map or does not contain a valid :status key.
• :error-confirmation will be used if an exception is encountered (with the exception being assoced into the map as :error).

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