enable to choose logger when auto instrumentation and logback

[tkmsaaaam]

Is your feature request related to a problem? Please describe.

I can not choose logger when using auto instrumentation and logback.

When it's setting like OTEL_LOGS_EXPORTER=otlp (default) and java -javaagent:/path/to/opentelemetry-javaagent.jar, all of loggers export to logging service (e.g. loki). So when I don't want to send some logs to loki (it depends on logger), I can't use auto instrumentation (especially log). I want to send only root logs to loki and I don't want to send SECURE logger. when below settings

<logger name="com.example" level="INFO"/>
<logger name="SECURE" level="INFO" additivity="false">  
    <appender-ref ref="SECURE_APPENDER"/>  
</logger>
<root level="INFO">  
    <appender-ref ref="STDOUT"/>  
    <appender-ref ref="FILE"/>  
</root>

Describe the solution you'd like

If I improve this repository, I make new options. like below
otel.instrumentation.logback.send-only-root-logger
otel.instrumentation.logback.chosen-loggers

Implement the decision whether or not to output based on the above options around the following

opentelemetry-java-instrumentation/instrumentation/logback/logback-appender-1.0/javaagent/src/main/java/io/opentelemetry/javaagent/instrumentation/logback/appender/v1_0/LogbackInstrumentation.java

Line 52 in c5cb948

callDepth = CallDepth.forClass(LoggerProvider.class);

it should be possible to filter out specific logger names in the future, here's the recent spec work outlining the proposal: https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/logs/sdk.md#loggerconfigurator

in the meantime, you could disable the logback autoinstrumentation and use the logback appender directly which should give you more control
