> Making it an interface and having an {{AbstractWrappingFunction}} will allow implementations to have different classes as base classes. Also, we should change {{FunctionUtils}} to work like {{StreamingFunctionUtils}} so that wrapping functions don't have to implement the methods of {{RichFunction}}.
> These tests are disabled for now because we cannot properly implement the required features:
>  - WindowFoldITCase.testFoldWithProcessWindowFunction() (Scala)
>  - WindowFunctionITCase.testRichProcessWindowFunction() (Scala)
>  - WindowReduceITCase.testReduceWithProcessWindowFunction (Scala)
> Because of the ignored tests I'm updating to "blocker".
