I got this idea when I run local build. I found it's difficult to find out specific message from lots of log messages, which mixes module-build-service logs and others emitted from underlying libraries. I think we might categorize logs using the log name, for example they could be:

• module_build_service.frontend: logs come from any part of MBS frontend
• module_build_service.handler.init: logs come from init handler.
• module_build_service.handler.wait: similarly, logs come from wait handler.
• module_build_service.resolver.db: logs come from db resolver.
• module_build_service.resolver.mbs: similar as above.

and so on.

BTW, to reduce the length of each log line, module_build_service could be just replaced with MBS.
