[elliott-davis]

• Updated README to document new vGPU license visibility features, including annotations for license status and a condition in ClusterPolicy.
• Introduced license collection logic in license_collector.go and corresponding tests in license_collector_test.go.
• Implemented metrics for license status updates in metrics_license.go and integrated it into the NodeMetrics workflow.
• Added condition management for vGPU licensing in license_condition.go, with tests to validate behavior in various licensing scenarios.
• Enhanced permissions in 0300_clusterrole.yaml to allow patching of node annotations.

This update improves visibility and management of vGPU licensing, facilitating easier diagnostics and compliance monitoring.
