Add comfyui

This PR adds support for ComfyUI on Akash Network

[anilmurty]

Thanks for this submission @zJuuu - tested it and it works. Just noted that there was no log output while the container was spinning up and eventually saw this (even though the comfyUI instance does come up)

[app]: [app]: [app]: [app]: --listen --port 8080 --gpu-only [app]: WARNING:root:WARNING: libtorch_cuda_cu.so: cannot open shared object file: No such file or directory [app]: Need to compile C++ extensions to get sparse attention suport. Please run python setup.py build develop

Going to go ahead and merge this anyway

@zJuuu - were you able to get the UI to generate an image (with defaults)? - I tried a couple providers (foundrystaking and eurplots) and get this error: Prompt outputs failed validation CheckpointLoaderSimple:

• Required input is missing: ckpt_name

[anilmurty]

Oh, I see - because there are no checkpoints included by default (?)

And tried to run again. I get to the kSampler stage now and see this error:

@anilmurty tried to debug this but don't know the reason xformers is not working yet. It works if you add --disable-xformers to the command line flags as a workaround. I provide a fix in the next few days

Thanks @zJuuu - separate weird issue I noted that only happens with this SDL (and I tested on mac). The Shell connects but tab-completion, text selection and bash history (up arrow to scroll history) don't work. Probably has to do with the bash config in the docker image (?) - will be great if these worked since devs that use this will want to download files and such through the CLI.
