[FLINK-1369] [types] Add support for Subclasses, Interfaces, Abstract
Classes
This PR rebased PR #236 to the current master.
Some tests were failing and I had a closer look. The original PR handled
interfaces and abstract classes without member variables as POJO types.
However, POJO types without members cannot be handled correctly and do also not
have members that can be referenced as keys or fields.
I changed the logic such that interfaces and abstract classes without
members are handled as GenericTypes.
I'm not so familiar with the TypeExtractor, so it would be good if someone
else could have a quick look.
