We need to support the message which is not included in the history

Describe the current behavior

While working with a long chain of AIApplication, the history of achain cause context overflow

    async def achain(self, **kwargs: Any) -> Conversation[T]:
        """
        Create a new Conversation object asynchronously.
        """
        with self as conversation:
            await conversation.asend(**kwargs)
            while conversation.last_turn.has_function_call():
                message = conversation.last_turn.call_function()
                await conversation.asend(
                    message if isinstance(message, list) else [message],
                )

            return conversation

Describe the proposed behavior

Ideally, we need to support the Turn class to exclude some messages in self.history to avoid context overflow. in some cases, the last message inside While-loop doesn't need asend() to be called

Example Use

async def crawl_website(url) -> Message:
   return Message(disable_history=True, content=website_content)

Additional context

By having that, I think we can save the cost while working with large AiApplication.
