Cancelling a python client job won't stop the job from running on the server

[freddyaboulton]

Describe the bug

If you cancel a job with the client, it will keep running on the remote server.

I think the reason is that cancel will only tell the thread that's pulling results off the queue that it should stop. It won't stop the thread that's connecting to the server.

Reproduction

Run the cancel_events demo (increase the sleep to 1 second so that you have time to cancel)

from gradio_client import Client
client = Client("http://127.0.0.1:7860")
job = client.submit(7, api_name="/fake_diffusion")
job.cancel()

You will see that the server keeps printing output in the console
