Add cAdvisor Docker Insights dashboard for monitoring container metrics

- Introduced a new Grafana dashboard JSON file for cAdvisor Docker Insights.
- Configured data source to use Prometheus for metrics collection.
- Included panels for monitoring running containers, CPU usage, memory usage, I/O operations, and network traffic.
- Added a heatmap panel to visualize container restarts over time.
- Set refresh interval to 5 seconds and default time range to the last 3 hours.
- Provided a description for the dashboard to enhance usability.
