Instrument extended open telemetry

[zeitlinger]

Fixes #14191

[zeitlinger]

I'm getting

class io.opentelemetry.javaagent.instrumentation.opentelemetryapi.v1_27.ApplicationOpenTelemetry127 cannot be cast to class io.opentelemetry.api.incubator.ExtendedOpenTelemetry (io.opentelemetry.javaagent.instrumentation.opentelemetryapi.v1_27.ApplicationOpenTelemetry127 and io.opentelemetry.api.incubator.ExtendedOpenTelemetry are in unnamed module of loader 'app')
java.lang.ClassCastException: class io.opentelemetry.javaagent.instrumentation.opentelemetryapi.v1_27.ApplicationOpenTelemetry127 cannot be cast to class io.opentelemetry.api.incubator.ExtendedOpenTelemetry (io.opentelemetry.javaagent.instrumentation.opentelemetryapi.v1_27.ApplicationOpenTelemetry127 and io.opentelemetry.api.incubator.ExtendedOpenTelemetry are in unnamed module of loader 'app')

@laurit can you give me a hint?

I thin you forgot to actually use the ApplicationOpenTelemetry155Incubator that you added. Have a look at

opentelemetry-java-instrumentation/instrumentation/opentelemetry-api/opentelemetry-api-1.0/javaagent/src/main/java/io/opentelemetry/javaagent/instrumentation/opentelemetryapi/ApplicationOpenTelemetry.java

Line 22 in 39137d1

OpenTelemetry instance = getOpenTelemetry127();

Thanks @laurit - can you check if this PR together with the SDK PR make sense (see ticket description)?
