Need some hook callbacks in server.py

[liusida]

Since #3297 doesn't have the potential to be merged, I'll close it again.

And, @comfyanonymous , can you simply add an empty callback function after ws connection is closed and after sending a sync to the client:

ComfyUI/server.py

Line 118 in c334122

self.sockets.pop(sid, None)

and

ComfyUI/server.py

Line 617 in c334122

self.send_sync("status", { "status": self.get_queue_info() })

so that I can write a custom node to override this callback function and do some clean up?

Or any other suggestion to save resource when multiple instances of ComfyUI are running concurrently?
