Description of problem:

ClusterInstance CRD does not have default values for cluster-level and node-level templateRefs. The expected values should be, 

spec.templateRefs:
  - name: ai-cluster-templates-v1
    namespace: open-cluster-management

spec.nodes.templateRefs:
    - name: ai-node-templates-v1
      namespace: open-cluster-management
