Switch to multi-arch build and images

[mahnunchik]

It's been two years since the last discussion of this topic #131

All the software I use has switched to multi-architecture images in docker world. The technology has become stable over the past two years.

Maybe it makes sense to switch to a multi-arc build and multi-arch images. This will greatly simplify the build step of add-ons and save "kilometers" of documentation.
