It turns out that alpine dropped support/updates for the aarch64 image.
Instead they have been using the arm64v8 notation for quite a while,
which resulted in breaking our recent aarch64 builds due to missing
dependencies/updates.
Both arches are exactly the same, aarch64 was created originally by Apple
and arm64 by GNU. The backends have been merged by now and the arm64 became
the de facto standard.
* Adjust arm32v6 and aarch64 docker images to match the hello-world image
* Update from master, fix potential bug in push-images target, and update storagenode deploy to handle arm64 image
