Multiple jax-rs instrumentations

[pavolloffay]

There are multiple jax-rs instrumentation:

1. https://github.com/opentracing-contrib/java-jaxrs
2. https://github.com/uber/jaeger-client-java/tree/master/jaeger-jaxrs2 @yurishkuro
3. https://github.com/opentracing-contrib/java-dropwizard/blob/master/dropwizard-opentracing/src/main/java/io/opentracing/contrib/dropwizard/ServerRequestTracingFilter.java @bhs

https://github.com/opentracing-contrib/java-jaxrs ropadmap:

• use with combination with https://github.com/opentracing-contrib/java-web-servlet-filter to capture errors like no URL mapping, unauthenticated requests, exceptions in filters...
• in-process propagation, as intermediate solution maybe use spanmanager , once Standard(s) for in-process propagation opentracing/specification#23 is solved use what standard says.

Would it make sense for you to reuse java-jaxrs in 2. and 3.?

Yes, but I would wait for things with span manager / global tracer to settle.
