Use opentelemetry-java without ThreadLocalStorage

[johnpoth]

Hey guys awesome project!

I was wondering if there was a way to use this library without relying on all the ThreadLocalContextStorage stuff. We have a lot of Threads in our project and it is a nightmare to debug when scopes aren't closed in the same thread.

I feel like https://opentelemetry.io/docs/languages/java/instrumentation/#create-nested-spans is the closest I've found but there is a call to Context.current() so not quite :)

Thanks !
