Hi
I would like to propose a change in the kafka-stream summary log。 Now the summary of stream-tread is record every two minutes, and not support close or update intervals. When the kafka is running， this is absolutely unnecessary and even harmful since it fills the logs and thus storage space with unwanted and useless data. I propose adding a configuration to control the output interval or disable it KIP： https://cwiki.apache.org/confluence/display/KAFKA/KIP-1049%3A+Add+config+log.summary.interval.ms+to+Kafka+Streams
