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.
