Cloudfare tunneling for permament link

[natolambert]

another utility for demos: just pushed cloudflared-tunnel to pypi. Works similarly to public gradio links, but uses cloudflare and links never expire. To use:

#! pip install cloudflared-tunnel

import gradio as gr
import cloudflared_tunnel

with gr.Blocks() as demo:
    # setup your demo here
    ...

with cloudflared_tunnel.run() as port:
    demo.launch(show_api=False, server_port=port)

It will spit out something like the following:

 * Running on https://considering-fame-from-household.trycloudflare.com/
 * Traffic stats available on http://127.0.0.1:9835/metrics
Running on local URL:  http://127.0.0.1:8972/

To create a public link, set `share=True` in `launch()`.

Then you can use the url .trycloudflare.com to connect to your demo 🙂
