Implement Timeout Configuration for Response and Stream Waiting

[xgen20]

I suggest implementing the ability to configure the timeout for waiting for a response and waiting for a response stream. Because in my case, it's not always enough to receive a response from GPT-4 (chat to API version). The response sometimes takes 2+ minutes to write, and the Сhat Nio stops processing the stream after 1-2 minutes. And if the API doesn't send anything at all, it resets the request after 20+ seconds and makes a new attempt. I would like to have the ability to adjust this parameter for each channel, as well as the parameter for the maximum waiting time for the stream.
