> Add an integration test to validate windowing behavior against real runners, in particular WRT GroupByKey operations.
> This entails writing small batch test pipelines that assign event times, and window into those transforms. Windows are assigned by the the runner as per the given windowing strategy.
> Code should be added in the sdks/go/test directory [https://github.com/apache/beam/tree/master/sdks/go/test/integration/primitives]
> and hooked up so that they're run as part of the post commit tests. 
> In particular, a multi-window case with a sliding window, and a lifted combiner (like stats.Sum) should be written. It's unlikely the current Combiner Lifting implementation takes windows into account correctly, leading to correctness issues when they are used simultaneously.
