CI: test multi-arch cluster / alternatives arch

[VannTen]

What would you like to be added

We have hash for other arch than x86, but it's not tested, and some things are broken (download delegation, for instance, though I'm working on that).

Why is this needed

This should not actually be that hard to have multi-arch working properly, we just need to be a bit more mindful of using Ansible correctly (aka, consider that variable are host local, not constant across all hosts).

@ant31 Besides working on the kubevirt manifests in .gitlab-ci/kubevirt.yml, maybe we need some change on the test cluster at qemu level ?
