[PR] [improve] PIP-467: Convert pulsar-broker module logging from SLF4J to slog [pulsar]

["merlimat (via GitHub)" <gi...@apache.org>]

merlimat opened a new pull request, #25535:
URL: https://github.com/apache/pulsar/pull/25535

   ## Summary
   - Convert 210 files in the `pulsar-broker` module from SLF4J to slog structured logging
   - Add derived loggers with class-level context attributes (e.g. `topic`, `subscription`, `state`) so that related log lines carry the same structured context automatically
   - Subclasses that previously inherited a `protected final Logger log` from their parent now declare their own logger that chains the parent's context via `Logger.get(SubClass.class).with().ctx(super.log).build()`, so the logger name matches the actual runtime class while still inheriting parent attributes
   - Rename leftover generic `argN` attrs to meaningful names; strip stale SLF4J `{}` placeholder text from log messages
   - Use short form `log.level("msg")` when no attributes are present
   
   ## Test plan
   - [x] `./gradlew :pulsar-broker:compileJava` passes
   - [x] `./gradlew :pulsar-broker:checkstyleMain` passes
   - [x] `./gradlew :pulsar-broker:compileTestJava` passes
   - [x] `./gradlew :pulsar-broker:checkstyleTest` passes
   - [ ] CI passes
