Add multiarchitecture support

[tedivm]

This builds off of the PR in the upstream repo.

It will not work until that has been merged and the images published.

I've created a new project called Multi-Py that builds multiplatform containers.

The new organization now has the following multi platform images-

• uvicorn
• gunicorn
• gunicorn running uvicorn
• oso

They're pretty stable now should anyone want to use them, and should be a mostly drop in replacement for this project.

Very useful

Thank you! 🍰

Now that Uvicorn supports managing workers with --workers, including restarting dead ones, there's no need for Gunicorn. That also means that it's much simpler to build a Docker image from scratch now, I updated the docs to explain it.

Because of that, I deprecated this Docker image: https://github.com/tiangolo/uvicorn-gunicorn-fastapi-docker#-warning-you-probably-dont-need-this-docker-image

That also means that by building your Dockerfile based on the official Python you will get multi-arch by default. 😎

Given that I'll close this one, but thanks for the effort! ☕
