Cascading changes for compatibility
@fhueske and me are working on getting Cascading to run on top of Flink.
These two commits introduce changes that were necessary to make the translation
possible.
Up to debate is the second commit, which loads the userclassloader before
calling `configure` on an InputFormat. This is necessary because Cascading has
its own interface that needs to be wrapped inside a Flink `InputFormat`.
Usually, all dependencies are loaded upon instantiation of the class. However,
Cascading loads its own input format while `configure(config)` is called (via
the class name inside the passed config). Without the changes, this leads to a
ClassNotFoundException.
Let me know what you think about it.
