test: migrate the openshift virt test to a new cluster

The old one is going to be decommissioned. I only changed:
- extracted the storage class to a variable
- adjusted the openshift yaml file to what I was given in the UI
  - most importantly, we now use an instancetype to specify the
    resource requirements instead of doing it manually
  - the network is called default, instead of nic0 on this cluster
- we are downloading the oc and virtctl clients from the new cluster
  so the versions match
