[dd-trace-ot] Ability to customize LogHandler when using the java agent

[ghostdogpr]

I would like to customize the logic of extractError in DefaultLogHandler:

dd-trace-java/dd-trace-ot/src/main/java/datadog/opentracing/DefaultLogHandler.java

Line 45 in a760c68

if (map.get(ERROR_OBJECT) instanceof Throwable) {

For that, I can simply create my own custom LogHandler and then create a new DDTracer:

val ddTracer = DDTracer.builder().logHandler(new CustomLogHandler()).build()

But when I do that it fails with: Datadog Tracer already installed by dd-java-agent. NOTE: Manually creating the tracer while using dd-java-agent is not supported.

Is there a way to pass a custom LogHandler when using the agent?
