Allow logging via OpenTelemetry

[knutwannheden]

Description
Allow the smallrye-opentracing to optionally register a logging handler which would add all logging events above a given threshold level to the currently active tracing span (if any).

The user would use dedicated config properties to enable this feature (disabled by default) and configure the threshold level to use to filter the events to log via OpenTracing.

I don't believe we'd implement this with OpenTracing, but we could look to do it with OpenTelemetry when that's added to Quarkus

I changed the title to refer to OpenTelemetry, as that's the tracing approach we'd implement this idea with

Is it possible to help on this ?

@knutwannheden will close this issue because we plan to have support for OpenTelemetry Logging: #30712
