class UnwrappingAggregateFunction[Input] extends AggregateFunction[ValueWithContext[StringKeyedValue[Input]], AnyRef, AnyRef]

This class unwraps value from input's KeyedValue.

NOTE: it would be much cleaner if we evaluated aggregateBy here. However, FLINK-10250 prevents us from doing this and we *have* to compute it beforehand

When using this class it's important that aggregator, passedType and unwrap must match: unwrap result is of passedType and can be processed by aggregator
