Reconcile C4 models

[whiteheaddmark]

MW and AM independently created RADPS C4 models. The models differ slightly and should be reconciled. Reconciling the models will improve our common understanding of how the system will work.

• Meet to discuss and reconcile the differences and address open questions.
• Settle on one C4 model that includes Context, Container, Component, and Deployment views.
• Update the backlog with any stories that result from reconciling the models.
• Make the model publicly available.

The approach to take for diagramming a microservices architectural style depends upon the ownership of the individual services, and whether you see them as an implementation detail inside a single software system or as separate software systems that are (or could be) owned by separate teams.
-C4 docs

The diagrams currently under the k8s section of the wiki follow the latter approach. Mapping out the relationship between deployed services in terms of the implementation details (i.e., pods running on nodes in some configured cluster) does still leave undefined questions about service ownership and the appropriate outer boundary of the system context.
