    SAMZA-1386: Inline End-of-stream and Watermark logic inside OperatorImpl

    This patch contains the following changes:
    1. Refactor watermark and end-of-stream logic. The aggregation/handling has been moved from WatermarkManager/EndOfStreamManager to be inline inside OperatorImpl. This is for keeping the logic in one place.
    2. Now subclass of OperatorImpl will override handleWatermark() to do its specific handling, such as fire trigger.
    3. Add emitWatermark() in OperatorImpl so subclass can call it to emit watermark upon receiving a message or watermark.
