OpenTelemetry and other custom context support

[erkieh]

Hello,

I am evaluation usage in a Kotlin project.

Is there a way to persist custom context data along with a workflow start?
I have cases where i would like to rebuild the context when executing steps and child workflows.

These kinds of interceptors/handlers could of course be used for adding open telemetry tracing.

Rebuild the DBOS Context or rebuild your own context?

[erkieh]

My own. Mainly open-telemetry and auth context.

Other DBOS implementations have auth context, but those haven't been implemented in DBOS Java yet. Tracked by #167
