Clarified example architectures

I clarified the example architectures section to cover the two primary
architectures assumed throughout the installation guide. This patch
fixes the immediate issue of operators not understanding assumptions
made by the guide. A future patch for this bug will include improved
text and diagrams based on example architectures chosen for Icehouse.
