ci: Add basic k8s arm tests

Those tests are covering:
* go runtime:
  * cloud-hypervisor
  * qemu
* rust runtime:
  * cloud-hypervsuor
  * dragonball

The tests are running on a ARM64 baremetal machine, which has vanilla
kubernetes deployed.

I don't want to use the same machine for devmapper tests / cri-o tests,
as that would require deploying and re-deploying k8s there, which is not
exactly optimal for a baremetal machine.
