zhouchong 6e16438a57 [Feature] implement log channel separation and request log level system (#7190)
* feat: implement log channel separation and request log level system

* fix: log system improvements based on review

* add request_id to error logs, use RequestLogLevel enum, and unify logger implementation from utils to logger module
