[Feature Request] Disable content recording in tracing

[prise6]

Is your feature request related to a problem? Please describe.
When tracing with promptflow, is it possible to disable content recording (i.e. inputs and outputs of LLM) while still logging traces ?

Describe the solution you'd like
Similar to :

from langchain_azure_ai.callbacks.tracers import AzureAIInferenceTracer
tracer = AzureAIInferenceTracer(
        connection_string="...",
        enable_content_recording=False,
)

Describe alternatives you've considered
I consider switching off promptflow tracing when serving and using langchain_azure_ai but:

1. i'm not sure how to get it work : there are some collisions in tracer init ?
2. i can use other framework than langchain

Additional context
I don't understand why there are two similar project with Azure AI (or AML/AI Foundry) to trace LLM apps ?

Thanks,
