Description

Currently every two minutes for every stream thread statistics will be logged on INFO log level. 

2024-04-18T09:18:23.790+02:00  INFO 33178 --- [service] [-StreamThread-1] o.a.k.s.p.internals.StreamThread         : stream-thread [service-149405a3-c7e3-4505-8bbd-c3bff226b115-StreamThread-1] Processed 0 total records, ran 0 punctuators, and committed 0 total tasks since the last update 

This is absolutely unnecessary and even harmful since it fills the logs and thus storage space with unwanted and useless data. Otherwise the INFO logs are useful and helpful, therefore it's not an option to raise the log level to WARN.
Please make the logProcessingSummary

• either to a DEBUG level log or
• make it configurable so that it can be disabled.
  This is the relevant code: https://github.com/apache/kafka/blob/aee9724ee15ed539ae73c09cc2c2eda83ae3c864/streams/src/main/java/org/apache/kafka/streams/processor/internals/StreamThread.java#L1073
