NR-134815 Treat OTel WithSpan annotation as Trace

[sdaubin]

NR-134815

Overview

There is a java OpenTelemetry library that contains a WithSpan annotation designed to work the same as our Trace annotation. By adding support for this annotation we increase our adoption of Otel. It allows customers to use this open source annotation instead of our proprietary annotation (in many cases).

I think we can defer suppressing this instrumentation (otel.instrumentation.opentelemetry-instrumentation-annotations.exclude-methods) and adding support for otel.instrumentation.methods.include until later.

Note that OTel properties can be set through environment or system properties, like our agent, and eventually through a config file. We can use our existing otel instrumentation model to get access to the normalized version of the instrumentation settings to include and exclude methods and pass those to the core agent through the bridge.
