Description

Either types are recurring patterns and should be serialized efficiently, so it makes sense to add them to the core Java API.

Since Java does not have such a type as of Java 8, we would need to add our own version.

The Scala API handles the Scala Either Type already efficiently. I would not use the Scala Either Type in the Java API, since we are trying to get the flink-java project "Scala free" for people that don't use Scala and o not want to worry about Scala version matches and mismatches.
