[AGE-166] Add inputs and outputs to the exported data in tracing and generation view

[mmabrouk]

Currently only the following information is exported in the tracing and generation view:

variant,environment,status,created_at,latency,tokens,cost
app.default,playground,OK,2024-04-28T19:09:15.735000Z,0.73,37,0.000063
app.default,playground,OK,2024-04-28T19:09:27.134000Z,0.736,37,0.000063
app.default,playground,OK,2024-04-28T19:09:30.456000Z,0.989,77,0.00013099999999999999

We would like to add in addition to these the inputs and outputs for the traces in the trace view, and the inputs and outputs for the generations in the generation view
