Description of changes
Add two new report generators to analyze integration test metrics from DynamoDB:
generate_launch_time_report: Queries ParallelCluster-IntegTest-Metadata table to analyze cluster creation time and compute node launch times. Generates statistics grouped by OS and test name with time-windowed aggregation to achieve consistent result with os rotation.
generate_performance_report: Queries ParallelCluster-PerformanceTest-Metadata table to track performance data (OSU, StarCCM) by node count over time.
Both generators output Excel reports using pandas/openpyxl for easy analysis and visualization. Reports are automatically generated when JSON reports are requested via test_runner.py.
Tests
We are able to generate excel files at the end of integration tests
