Docker multi-arch support on CI

The linux/arm64 CI workflow exceeded the GitHub Actions 6 hours of execution time limit because of the qemu emulation.

So it will be temporarily disabled until actions/runner-images#5631

However, I could use temporarily a local arm64 machine to build and push the multi-arch images.

As you are probably aware, if you built it on a separate machine, you'll need to run a separate docker manifest (https://docs.docker.com/engine/reference/commandline/manifest/) set of commands to build a new multi-platform tag, so you may want to put the arch type on the image tag, and then do a separate manifest for the main tag.

Apparently it is on the roadmap: github/roadmap#528

@markmandel Thanks for pointed that out! Yes I will do that as a workaround when the next Rust release comes in.

Update: Turns out that I don't have the arm64 machine anymore. But there is a possibility to perform Linux arm64 builds via Cirrus CI cirruslabs/cirrus-ci-docs#905 which is awesome! I didn't know until now.
https://cirrus-ci.org/guide/linux/

So I could add Cirrus CI integration to perform the Docker multi-arch update for linux/arm64. I will investigate a bit more. Even I'm considering the option of moving out to Cirrus CI. 😅

Update: I already did some experiments with Cirrus this week but I got a small inconvenience when building an image on the arm64 instance there. So I hope I can get this problem sorted out in some way. Otherwise, I will try to look for alternatives.

Update: It is happening #18

[joseluisq]

Full Docker multi-arch support via Cirrus CI using two (amd64/arm64) separate native containers is ready to work (see #19).
And since Rust 1.65.0 is now out then a new equivalent release should come in the next hours 💪

Oooh! Will keep an eye out. I've been building my own internally, but will be lovely to switch back to yours 😄
