Hi,

I followed the great recommendation here to use OTEL tracer / spans in my user SPI,
and I have 2 follow up questions:

1. Are there examples for injecting trace-id and other tracing headers to next services that are called with HttpURLConnection from or User storage SPI? (we're using Jaeger propagators)

2. How to set up local OTEL exporters to console (e.g on local docker environment when OTEL endpoint is not available)?
   I tried few env variables described here with KC_ prefix, e.g KC_OTEL_TRACES_EXPORTER, but it didn't seem to have an impact.
