Updated tutorial to latest versions

[jpkrohling]

This PR updates the scenarios to work with the latest changes to be introduced by @SevaSafris on the tutorial this is based on (yurishkuro/opentracing-tutorial#30).

This should be merged whenever that one is merged, to avoid the scenarios from being broken.

@SevaSafris, could you take a quick look at this one and see if this matches with your changes?

@jpkrohling, the changes to scenarios seem aligned to the work I did with the opentracing-tutorial. One comment though: tracer.close() still needs to be called. I ended up putting the JaegerTracer init in a try-resource block.

Even with 0.32.0? I think this shouldn't be necessary on that version, as I implemented a JVM shutdown hook that automatically closes the tracer instances.

This is now ready to be merged. @BenHall would you be able to review/merge this PR?

Thanks for the updates!

Oh, I was not aware of 0.32.0. Should I also then upgrade the java-opentracing-tutorial to 0.32.0? This will resolve the concern re code coupling to Jaeger.
