Work Description: HuangLED commented on issue #10081: [BEAM-8645] A test
case for TimestampCombiner.

R: @robertwb
PreCommit failed once but I don't think it is caused by my PR. (after all
we only added two tests, and they are disabled. Tested these two new cases on
local machine, they worked).

> When we have a TimestampValue on combine:
> {code:java}
> main_stream = (p
> | 'main TestStream' >> TestStream()
> .add_elements([window.TimestampedValue(('k', 100), 0)])
> .add_elements([window.TimestampedValue(('k', 400), 9)])
> .advance_watermark_to_infinity()
> | 'main windowInto' >> beam.WindowInto(
> window.FixedWindows(10),
> timestamp_combiner=TimestampCombiner.OUTPUT_AT_LATEST) |
> 'Combine' >> beam.CombinePerKey(sum))
> The expect timestamp should be:
> LATEST: (('k', 500), Timestamp(9)),
> EARLIEST: (('k', 500), Timestamp(0)),
> END_OF_WINDOW: (('k', 500), Timestamp(10)),
> But current py streaming gives following results:
> LATEST: (('k', 500), Timestamp(10)),
> EARLIEST: (('k', 500), Timestamp(10)),
> END_OF_WINDOW: (('k', 500), Timestamp(9.99999999)),
