@Fricounet can you please review this? I haven't found any connection.WithOtelTracing() calls anywhere.

[Fricounet]

LGTM! I intially implemented the withOtelTracing call so that it would be easy to enable otel tracing on this CSI sidecars but I never got the time to implement it and since now, most CSI drivers plugin support tracing on their side, having it on the sidecar's would be a bit redundant. So I'm not really surprised that nothing uses connection.withOtelTracingin this repo at least

I probably can't approve though since I'm not part of sig-storage 😅
