Fix day-2 playbook: Add KUBECONFIG environment to all task includes

All tasks that use kubernetes.core modules need KUBECONFIG set.
The day-2 playbook was including tasks without setting the
environment, causing 'Invalid kube-config file' errors.

Fixed by adding environment block to all include_tasks that
interact with Kubernetes API:
- ACM ClusterImageSets
- Clair disconnected configuration
- Catalogsource ACM policies
- Model configurations
- VMaaS validation
