JDBC Metrics instrumentation from opentelemetry-jdbc library

[robsonfirmino]

I am implementing manual JDBC instrumentation using opentelemetry-jdbc library in my project. I've noted that there is no metrics implementation in the current library (2.6.0-alpha-SNAPSHOT).
Is there some initiative to implement database metrics in the opentelemetry-jdbc library?

[trask]

Yes! @heyams is currently planning to implement the latest database semconv in the jdbc instrumentation (behind a flag for now until database semconv is marked as stable)

[robsonfirmino]

@trask Thanks for answer!
@heyams Do you have some branch started or are you waiting 'semconv' stable to start coding jdbc metrics?
I'm asking this because maybe I can contribute from some way.

Same here. Is there a way to enable these metrics as a preview?
They would be helpful to our observability stack.
