Support for multiple servers.

This is my selfish petition as someone who has a fleet of medium specs AI servers.

Newer and better models are getting released but there are often slower and hardware demanding. HiDream for example is arguably better than Flux at higher resolution but it is very slow for any inpainting workflow. Their E1 editing model is capable but not a true replacement for subtle inpainting.

I managed to build a comfy inpainting workflow utilizing all my servers running in parallel using the amazing ComfyUI-Distributed but failed to integrate it into Krita using the custom graph. Krita will only show the output of one server.

Even if HiDream is officially supported later by krita-ai-diffusion, it will be to slow with only one server, unless with a very beefy card.
