Jfr streaming version (#721) 
Resolves #707. Builds on #716. 

Turns out this wasn't a good first issue because there was some gradle
buildSrc work needed to add a file with the version that the source code
could read. Lifted the source for this from
[opentelemetry-java](https://github.com/open-telemetry/opentelemetry-java/blob/main/buildSrc/src/main/kotlin/otel.java-conventions.gradle.kts#L144-L165).
