In the infra env screens the hosts are called "hosts". In the cluster side they are called "nodes".

There is a good reason for it:

• the term "node" is a kubernetes term and it means "a piece of equipment on which kubelet is running and can accept workload". It is an actual entity which can be manipulated as anything else in the system (e.g. "oc get nodes" etc).
• the term "host" is a more high level term and it means "something, which if it will be installed will be recognized by kubernetes as a node. It might already be recognized as such or it might not yet."

We need to educate the user about the difference.
