Add a legend

[rogeruiz]

The rendered pages need a legend included to explain the various visual elements of the diagrams.

Below is a list of legend items for diagrams. Please discuss it in this issue.

If an item below is checked, it has been verified.

• circles - Actors
• arrows connecting components - One-directional data/information flow
• lines connecting components (without arrowheads) - Bidirectional data/information flow
• dotted lines - Data/information request that is system generated, rather than actor requested (e.g. authentication, or container creation)
• labels on lines/arrows - Description of the data/information being transferred
• square transparent boxes - Groups of components that together serve as a larger component
• blue boxes - Component (which may be comprised of sub-components)
• flags - External data components
• diamonds - Collections of VMs or Containers
