OTLP Integration for Tracing and Logs

[cpeliciari]

It would be a new feature aimed at integrating with OTLP. This would help us have systems with tracing alongside logs.

I think it’s feasible to create a new package “zapotlp” and, to maintain compatibility, we can create a new method WithSpan that returns a Logger. With this, we can build messages compatible with OTLP to be sent.

If interested, I can submit a PR.

Dependencies:

• go.opentelemetry.io/otel
• go.opentelemetry.io/otel/log
• go.opentelemetry.io/otel/sdk/log

Have you tried https://pkg.go.dev/go.opentelemetry.io/contrib/bridges/otelzap?

PS. Maybe the zap maintainers want to also review the package design and implemention?
