Add PostgreSQL and database pool metrics to telemetry 
- Create DatabaseMetrics module to collect PostgreSQL statistics
- Add metrics for database connection pool (size, idle, busy, queue)
- Add PostgreSQL connection metrics (active, idle, waiting)
- Add packets table metrics (size, row counts, operations)
- Add query performance metrics from pg_stat_statements
- Create enhanced Grafana dashboard with database visualizations
- Configure periodic measurements to collect metrics every 10 seconds

This provides comprehensive database monitoring including:
- Connection pool health and utilization
- PostgreSQL connection states and bottlenecks
- Table growth and dead tuple ratios
- Query performance statistics
- Database and table sizes
