[FLINK-2007] [streaming] Proper Delta policy serialization
The initial value passed to the Delta policy has to be serialized to be
transferred to the cluster. This change adds the standard Flink serializers for
that job. The API is preserved on the level of the `Delta`, but the
`DeltaPolicy` itself explicitly needs the serializer.
Test4 in`ComplexIntegrationTest` demonstrates and tests my change in action.

> Project: Flink
> Issue Type: Bug
> Components: Streaming
> Affects Versions: 0.9
> Reporter: Márton Balassi
> Assignee: Márton Balassi
> Labels: serialization, windowing
> Fix For: 0.9

>
> Currently we expect the data point passed to the delta function to be
> serializable, which breaks the serialization assumptions provided in other
> parts of the code.
> This information should be properly serialized by Flink serializers instead.
