> Exception Hierarchy for Streams

> Key: KAFKA-3125

>
> Currently Kafka Streams do not have its own exception category: we only have
> one TopologyException that extends from KafkaException.
> It's better to start thinking about categorizing exceptions in Streams with a
> common parent of "StreamsException". For example:
> 1. What type of exceptions should be exposed to users at job runtime; what
> type of exceptions should be exposed at "topology build time".
> 2. Should KafkaStreaming.start / stop ever need to throw any exceptions?
> 3. etc.
