Visualize desired landscape setup as YAML and/or graph

[In-Ko]

Description

Let's make our desired landscape setup more digestible by creating a graph with all components and their connections to each other. We will later use that to identify the necessary interfaces.

We can also write down the configuration in the form of fictional Kubernetes resources. We should think about the parameters that each component needs to receive and which information it can expose in the form of a status. Basically like: "How can the components communicate with each other through Kubernetes resources?"

Stretch:
We should use mermaid. https://mermaid.js.org/

Acceptance Criteria

Define ideal declarative state of our future setup, covering all components, their fields/interface + depdnencies
create followups for components we identify need more attention

Stretch: Let's do open-source (start practicing)

@robertgraeff Should we consider this done or will the stretch goal of using mermaid be addressed ? Not super critical for me though ...

[robertgraeff]

I would consider this done.

For this diagram, the arrangement of boxes and arrows is essential, to keep the diagram clear. Mermaid is great, but only special types of diagrams allow you to somehow control the arrangement of elements.
