Add image metadata to the OpenStack node-images.yaml as is defined in the related SCS standard

/kind feature

SCS standard scs-0102-v1-image-metadata describes what metadata (properties and tags) should be assigned to the image that is offered by the CSP.

These properties and tags are then evaluated by the Conformance Tests (script image-md-check.py).

CSPO supports a full list of create options, defined by the OpenStack API. Hence the node-images.yaml should include all mandatory properties and tags for each image.
