Issue Time Tracking

Worklog Id: (was: 365873)
Time Spent: 8h (was: 7h 50m)
> @RequiresTimeSortedInput DoFn annotation
> ----------------------------------------
>
> Key: BEAM-8550
> URL: https://issues.apache.org/jira/browse/BEAM-8550
> Project: Beam
> Issue Type: New Feature
> Components: beam-model, sdk-java-core
> Reporter: Jan Lukavský
> Assignee: Jan Lukavský
> Priority: Major
> Time Spent: 8h
> Remaining Estimate: 0h
>
> Implement new annotation {{@RequiresTimeSortedInput}} for stateful DoFn as
> described in [design
> document|https://docs.google.com/document/d/1ObLVUFsf1NcG8ZuIZE4aVy2RYKx2FfyMhkZYWPnI9-c/edit?usp=sharing].
> First implementation will assume that:
> - time is defined by timestamp in associated WindowedValue
> - allowed lateness is explicitly zero and all late elements are dropped
> (due to being out of order)
> The above properties are considered temporary and will be resolved by
> subsequent extensions (backwards compatible).
