Integration test can optionally consume cluster state as generated by the call to `osctl cluster create` and use it to discover nodes in integration tests. This means that now CLI tests can use that as discovery source, and API/K8s tests by default as well. Flat list of nodes is to be replaced by something more complex in the next iteration, but it's good for this PR. As a demo, add CLI test with multiple nodes (dmesg).
