What would you like to be added:
Components in GLK should generate Gardener Image Vectors when such information is found in the given OCM component descriptor.

Why is this needed:
GLK is already capable of processing OCM component descriptors, primarily to extract component and version information.
For images that are required by Gardener and extensions, e.g. those needed to create a shoot cluster, image vectors can be configured. They overwrite the location, allowing images to be consumed from an OCI registry mirror.
