We can't remove this as it's in the intf.ml file and is called in the test_executive itself. To minimise changes to the cloud engine we should keep the function as is below. In the GCP case, the function looks like it's just testing all the pods were deployed with nodes in them. Given that we've abstracted away the infrastructure from the test I assume this will now be done in the network runner (e.g. minimina or AWS), so we don't need anything other than a unit returning function, but we will need some process like this in the network runner that basically checks the network is ready to start the nodes.
