Description

FLINK-4624 updated Gelly's Summarization algorithm to use Either<NullValue, VV> in order to support types for which the serialization does not support null values. This required the use of explicit TypeInformation due to TypeExtractor. FLINK-4673 created a TypeInfoFactory for EitherType so the explicit TypeInformation can be removed.
