Currently Remoting Kafka Plugin produces a lot of logs by default due to logging of commands being sent and received. 

Jenkins Remoting offers a default Channel.Listener extension. IMHO it would be useful to modify the command logging logic:

• Command logging happens through Channel.Listener
• For master a standard Logging logic is used: https://github.com/jenkinsci/jenkins/blob/e4e06333ee3c4dcdf8c945f85691e1dbb639d5e7/core/src/main/java/hudson/slaves/SlaveComputer.java#L597
• For Remoting Kafka Agent fine grain logging is enabled via CLI argument or a system property (or by Logging level as in master)
