Closes#3770 from dguy/kafka-5652-produced
The iterator interface usage has some examples missing explicit close operation after usage. We should remind the user to do so because un-closed iterator will leave the underlying file descriptor open, thus eating up memory.

Closes#3604 from dguy/memory-management-docs
1. Remove rest deprecation warnings in streams:jar.
2. Consolidate all unit test classes' reflections to access internal topology builder from packages other than `o.a.k.streams`. We need to refactor the hierarchies of StreamTask, StreamThread and KafkaStreams to remove these hacky reflections.
3. Minor fixes such as reference path, etc.
4. Minor edits on web docs for the describe function under developer-guide.
