> Preregister ML types for Kryo serialization

> Currently, FlinkML uses interfaces and abstract types to implement generic
> algorithms. As a consequence we have to use Kryo to serialize the effective
> subtypes. In order to speed the data transfer up, it's necessary to
> preregister these types in order to assign them fixed IDs.
