Support slog logger

[DAcodedBEAT]

Describe the feature

Add support for the Structured Logging (slog) standard library in Go.

Motivation

Implementing support for slog will align this module with Go's ecosystem standards, enhancing its portability and interoperability.

note: This feature would also allow the module to accommodate other logging requests, as slog's backend interface (Handler) can be adapted to support various popular logging packages. For example, existing integrations include https://github.com/samber/slog-zap and https://github.com/samber/slog-zerolog.

@zstone12, I think you should considering supporting OTel Go Logs API: https://pkg.go.dev/go.opentelemetry.io/otel/log

@pellared - just for my understanding, why can't the OTel Go Logs API be implemented as a slog Handler and use slog as the common interface?

Take a look at https://github.com/open-telemetry/opentelemetry-go/blob/main/log/DESIGN.md#reuse-slog

Therefore, you can use slog as the interface by using https://pkg.go.dev/go.opentelemetry.io/contrib/bridges/otelslog.
However, it will involve a translation layer.

Given this is an opentelemetry repo I think you can simply integrate using OTel Logs API and not couple to different logging libraries.

PS. Take my words with a grain of salt as I never used nor tried using gorm.io/plugin/opentelemetry.

PPS. Thanks to you I updated the design doc as I was outdated a little: open-telemetry/opentelemetry-go#6206
