[Feature Request] Get tracing info via python interface

[derkmus-tomtom]

Is your feature request related to a problem? Please describe.
Currently it is possible to view tracing of e.g. an LLM call via an UI. It is not possible, as far as I know, to get this info with some calls in your python script.

So I am talking about getting the info that is in the UI for example here: https://github.com/microsoft/promptflow/blob/main/examples/tutorials/tracing/llm/trace-llm.ipynb. There are no calls to pf.run, so you cannot use pf.get_details

Describe the solution you'd like
A promptflow function that you can call with a trace id that returns the info that you can find in the trace UI
