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.
