Zander Chase 4ee47926ca Add on_chat_message_start (#4499) ... ### Add on_chat_message_start to callback manager and base tracer Goal: trace messages directly to permit reloading as chat messages (store in an integration-agnostic way) Add an `on_chat_message_start` method. Fall back to `on_llm_start()` for handlers that don't have it implemented. Does so in a non-backwards-compat breaking way (for now)		2023-05-11 11:06:39 -07:00
