metal3: Make NUM_NODES configurable

So far, NUM_NODES in feature_tests have been set to 4, but this could be
made configurable, so that we can add different number of nodes for
different tests. For e.g. Scalability test could reuse the same
workflow, but it will need a much higher number of nodes.
