refactor: full refactoring for the whole project

[MaikoTan]

Description

This is a full refactoring for the whole project. It can be summarized as the following:

• Replace aiohttp to requests, also removed asyncio and all asynchronized code

  The async causes many problems with gradio and fastapi that we required to communicate with the Stable Horde side. Replacing it with the old school requests solved this.

• Split the UI Page into Worker and User

  So it is able to manage your user resources in the WebUI now

• Apply Interactive Outputs feature on result image receiving

  This might be a bit improvement for the performance.

Yes! It would be great if you could help.

Currently this PR is working, but I want to add more things before merging it:

1. Model (checkpoint) list, with download feature. I am not sure how to implement the download feature or even the list itself. I think the easy way is to write js script and fetch models from stable horde, then add an <a> tag point to the download link besides the model name as a download button.
2. A full-featured user page, at least there should be names, kudos, generated images count, workers list (with maintenance mode switching). I didn't found a way to verify "which worker is this sd-webui instance", so maybe we should just listing all workers belongs to the current user.
