Simplify Docker containers build and publish

[andrewlukoshko]

Since we originally invented Docker container build scripts there are a lot of new technologies available to make this process simplier and easier to maintain. I'd propose to consider the following:

• Move containers build process to GitHub Actions to make it transparent
• Use QEMU to build for different architectures
• Simplify and unify containers publish process as we need to publish to different places:
  • Docker Hub Official
  • Docker Hub AlmaLinux repo
  • Quay.io

We should consider a self-hosted/FOSS solution instead of relying on GH/their runners.

If they modify how they handle certain aspects (ex, billing), it could become a pain point.

Ideally, we don’t want to rely on $BIGCORP and their goodwill to continue doing our work and should improve our pipeline to be as independent/FOSS heavy as possible.
