🚀 Feature: Log prompts while preserving user PII with Presidio about openllmetry

Thanks @clemlesne that's a great idea!
We can maybe add it at the SDK level on the span processor. I wonder if there's any latency or performance impact.

Presidio works very badly on languages other than english. just a heads up. we ended up using another PaaS MSFT service (Cogservices). But perhaps it would make sense to have a plugin interface process PII before loggin it.

Or potentially this might be something that should be done on the ingestion side? I worry about creating a significant overhead on production devices.
