> Currently, streaming job with bounded input can't be terminated automatically and TestDataflowRunner
can't handle this case. Need to update TestDataflowRunner so that streaming integration test
such as WindowedWordCountIT can run with it.
> Implementation:
> Query watermark of each step and wait until all watermarks set to MAX then cancel the
job.
> Update:
> Suggesting by [~peihe0@gmail.com], implement checkMaxWatermark in DataflowPipelineJob#waitUntilFinish.
Thus, all dataflow streaming jobs with bounded input will take advantage of this change and
are canceled automatically when watermarks reach to max value. Also Dataflow runners can keep
simple and free from handling batch and streaming two cases.
