Happy New Year! I updated this PR with an integration test similar to the one in `JaegerTracerConfigurator`, starting the tracer in a cluster. I then discovered that the OTEL tracer was not being closed correctly, and there was a leaking background thread from the batch span exporter. Turned out that OTEL's [OpenTracing Shim](https://github.com/open-telemetry/opentelemetry-java/tree/main/opentracing-shim) class by design [will not close the actual tracer](https://github.com/open-telemetry/opentelemetry-java/blob/v1.21.0/opentracing-shim/src/main/java/io/opentelemetry/opentracingshim/TracerShim.java#L98), so when `CoreContainer#shutdown()` is called, the tracer is left open. The workaround I chose is to wrap the `TracerShim` in a thin `ClosableTracerShim` delegate class that will properly close the tracer through the SDK. Seems to work, though I have yet to test this version of the module with a real collector. I also had to adjust the dependencies, since I started using the SDK directly and not only through ENV auto-config. -- This is an automated message from the Apache Git Service.
