OpenTelemetry instrumentation

Discussed in #1267

Hello!

I was looking at how I might get instrumentation out of the library, both traces and metrics. I noticed that the ch-go "low level" API instruments various code paths, like https://github.com/ClickHouse/ch-go/blob/main/query.go#L609. I did at first think this library used those code paths, but as far as I can tell it is only sharing the driver.Conn interface definition and not using the ch-go client.

Is there any plan to do the same sort of instrumentation in this library? Would you like contributions in this area?

Hi, it’s a good idea, but I wouldn't want the library to be use to a specific tracing implementation like opentracing, but to provide an interface like in pgx. (https://pkg.go.dev/github.com/jackc/pgx/v5#QueryTracer)
