> Key: BEAM-8550

> Project: Beam
> Issue Type: New Feature

> 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).
