session_state reuse

[gaborvar]

Hi @fujita-h ,

Thank you for the cosmosdb chat history feature.
I rely on the session_state variable to keep the backend informed about earlier calls. Session_state is the only data that travels through the call chain to run_until_final_call() where I do some extra work which needs status set by my previous calls.
To minimise collision surface with other features I kept my state in a separate key within session_state: session_state['be_messages']

Would you consider using a dict key like session_state['chat_history_id'] instead of session_state to allow the state of multiple features to coexist ?
