[FLINK-3379] [FLINK-3415] [streaming] Refactor TimestampExtractor
This pull request divides the TimestampExtractor into two separate classes
- one class handled periodic watermarks
- the other class handled watermarks triggered by individual elements
This also makes sure that any timestamp assigner / watermark generators
cannot generate
negative watermarks.
This also adds tests for the operators that run the timestamp extractors.
