[FLINK-1147][Java API] TypeInference on POJOs
The TypeExtractor now also fully supports generic POJOs and tries to get
missing types by using type inference.
Functions can look like:
```
MapFunction<PojoWithGenerics<Long, T>, PojoWithGenerics<T,T>>
MapFunction<Tuple2<E, D>, PojoTuple<E, D, D>>
MapFunction<PojoTuple<E, D, D>, Tuple2<E, D>>
```
POJOs can contain fields such as:
```
public PojoWithGenerics<Z, Z> field;
public Z[] field;
public Tuple1<Z>[] field;
```
If you have ideas for other test cases, I'm happy to implement them.
