Feature request: Throttle and/or pause Comfyui mid-generation.

I'm running some animatediff worklows that can take a whole day to process. If i need my gpu for anything else i either have to wait for it to complete or cancel it and restart the process. This makes me lose any progress on whatever node it was currently on which could cost me hours.

It would be very useful to be able throttle performance so that the gpu is not pegged the whole time.

Being able pause mid generation and then unpause later would also be hugely beneficial.
