SkipEval: Added exception to be raised by a feedback function to indicate that it should be skipped and not aggregated. This is for use cases were the feedback function is evaluated multiple times on different data and the determination of whether an evaluation on one piece of data should be skipped is done in the feedback implementation itself. Note the related existing feature if_exists to skip the entire feedback function for a whole record.
