commons: kustomize and plain kubernetes integration

[schwobaseggl]

ToDos in various repos

Projects

• Project.SPEC_CHOICES (for Project.spec_type) must be extended to include plain and kustomize
• Deck detection is different for plain/kustomize projects: Recursively look for kustomize.ya?ml files
• Detected Deck objects must be disablable (add field disabled)
• Do not expose disabled decks to common users via API
• Allow kustomize.yaml to be written in the frontend (like helm overrides!), possibly using the same model/field

Manifests

• Additional if-branches for the additional specTypes of a project in generator.py

Cli

• disallow disabled decks to be installed (should not come from API!)

Frontend

• Provide field to select Project.specType (helm, plain, kustomize)
• Provide checkbox for Deck.disabled
• If deck is disabled, hide it from common users, only show it to admins
• Adapt helm overrides view to write kustomize.yaml

Commons

• Analoguous to helm, probably some utils are needed by both the projects and manifests service when it comes to parsing/rendering manifests
