IsFBC will determine if an index image uses the File-Based Catalog or SQLite index image format.

RenderRefs will invoke Operator Registry APIs and return a declarative config object representation of the references that are passed in as a string array.

ValidateAndStringify first converts the generated declarative config to a model and validates it.

DefaultIndexImage is the index base image used if none is specified.

defaultIndexImageBase is the base for defaultIndexImage.

DefaultInitImage is the default image to be used in the registry init container.

BundleDeclcfg represents a minimal File-Based Catalog.

FBCContext is a struct that stores all the required information while constructing a new File-Based Catalog on the fly.
