> In Kafka 0.10.1.0 the toString method of KafkaStreams class has been implemented mainly
to ease topologies debugging. Also,  the streams Metrics has been exposed to public API.
> But currently theres is no way to monitor kstreams tasks states, assignments or consumed
offsets.
> I propose to expose the states of active tasks to the public API KafkaStreams.
> For instance, an application can expose a REST API to get the global state of a kstreams
topology.
