Consistent name for Trace/Span ids getters with the specification (#2721) 
See https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/trace/api.md#retrieving-the-traceid-and-spanid

Not breaking change since methods were just renamed anyway.

OpenTelemetry SDK Extension Java Flight Recorder (JFR) Events

Create JFR events that can be recorded and viewed in Java Mission Control (JMC).

  • Creates Open Telemetry Tracing/Span events for spans
    • The thread and stracktrace will be of the thead ending the span which might be different than the thread creating the span.
    • Has the fields
      • Operation Name
      • Trace ID
      • Parent Span ID
      • Span ID
  • Creates Open Telemetry Tracing/Scope events for scopes
    • Thread will match the thread the scope was active in and the stacktrace will be when scope was closed
    • Multiple scopes might be collected for a single span
    • Has the fields
      • Trace ID
      • Span ID
  • Supports the Open Source version of JFR in Java 11.
    • Might support back port to OpenJDK 8, but not tested and classes are built with JDK 11 bytecode.
