'make manifests' attempts to generate all airshipctl API types,
but several types throw errors and the resulting CRDs can't be
properly generated. This change:
- updates the controller-gen version to pull in a bug fix for the
error 'map values must be a named type, not *ast.StarExpr'
- modifies the Templater type's Values member to be of type JSON
since controller-gen does not support map[string]interface{},
and unmarshals it separately in the templater itself
- adds 'image_repositories' to the VersionsCatalogueSpec struct
to ensure it doesn't get deleted from the schema when manifests
get regenerated
- checks in generated copies of all CRDs from airshipctl's API
types, not just catalogues, to be used for validation
Closes: #574
