[FLINK-2788] [apis] Add TypeHint class to allow type-safe generic type
parsing
This adds the `TypeHint` as a type-safe way to create `TypeInformation` for
generic types. I think it should gradually replace the `TypeInfoParser`.
Generic type infos can be created via
```java
TypeInformation<Tuple2<String, Double>> info = TypeInformation.of(new
TypeHint<Tuple2<String, Double>>() {});
```
This creates an inline class that captures the generic parameters, and
fetches them via the TypeExtractor.
*This pull request is in preparation for improving the streaming example.*
