CODEOWNERS strategy/design for landscape-graph

[halcyondude]

cncf/landscape-graph is home to a variety of things.

• applications (both utility and end-user facing)
• daily update of landscape.cncf.io, sync'd and cleaned for import to the graph
• graphql schema definitions (source of truth)
• data model artifacts meant for both humans and robot consumption
• Sub-Graph Modules
