Jaeger (opentracing) integration

[Marx2]

Is your feature request related to a problem? Please describe. According to documentation I've successfully enabled tracing to micrometer and see data in /actuator/prometheus endpoint and some metrics in /actuator/metrics endpoint. So far so good. Now I'd like to see those traces in Jaeger UI. I've added dependency

<dependency>
            <groupId>io.opentracing.contrib</groupId>
            <artifactId>opentracing-spring-jaeger-cloud-starter</artifactId>
            <version>3.2.2</version>
</dependency>

and I see in Jaeger UI (from all services) REST calls, database calls, queue calls and many others . Unfortunately graphql calls are missing

Describe the solution you'd like I'd like to see graphql calls in Jaeger UI

Describe alternatives you've considered Current tracing works but i unusable in Jaeger

Additional context The best would be property which enable Jaeger (opentracing) integration on demand, as not everybody is using Jaeger (while it seems like a standard widely used) As we already have metrics, we need to make them compatible with jaeger. Current jaeger libraries push data to Jaeger database. How can we push GraphQL metrics too?
