This takes advantage of version catalogue replacement, which was added to
airshipctl in the changes below. It also refactors the kustomize structure
a bit to support that well.
This adds a treasuremap clusterctl function, which kustomizes the same function
from airshipctl to correct for paths. This replaces the previous
site-level clusterctl entrypoints.
This gives each type and site a catalogues entrypoint, which are wired together
(site inheriting from type, and network-cloud from airship-core) for
inheritance. Each phase that needs catalogue-based replacement now
pulls in its' site's catalogues definition, and then applies any
phase specific overrides only when necessary.
