Opentelemetry instrumentation for sql drivers including postgresql about kine HOT 2 OPEN

I will admit to being somewhat reluctant to add otel to kine. We already struggle with otel library compatibility in k3s between what is needed by kubernetes, etcd, and containerd, and have in the past had to maintain parallel kubernetes-minor-specific branches in order to resolve dependency conflicts. I am concerned that adding otel here will require similar juggling.

Are you not able to get the information you need from the Kubernetes apiserver's etcd client otel traces?

Sorry for late follow up on this. We're struggling with a lengthy diagnostic of performance and stability issue in our use-case around kine multi-server multi-az cluster. We're currently blocked with the otel instrumentation of the client k8s api server etcd. I hope I'll be able to share sample traces when we managed to get past the environment problems.
