Spaceflight Tutorial's kubeflow.yaml Nodes Not Using Node Namespace

[cupdike]

In the Spaceflight Tutorial (spaceflights starter, v0.18.3), kubeflow.yaml has unqualifed node names like model_training which don't align with the actual namespaced node names defined in the pipeline--such as data-science-active-modelling-pipeline-train-model-node. Accordingly, changing things like the resource attributes have no effect after compiling unless the correct node names are manually adjusted.
