Demonstrate usage of Github Actions Plugin for test fliprate calculations.

• flaky-test-analysis-examples workflow to demonstrate the usage of the plugin
  • Examples with existing test_history.csv and JUnit test result files
  • Heatmap images uploaded as heatmaps artifact
• full-workflow workflow to demonstrate flaky test analysis with previous test result artifacts
  • Download and unzip previous test result artifacts with download_artifacts.py
  • Upload test result and heatmap artifacts
• full-workflow-with-download-plugin to download artifacts with dawidd6/action-download-artifact
  • Latest artifact zip contains all of the history -> download latest zip for flaky test analysis
  • Upload heatmaps and append current test result to the artifact

• Create test_history.csv with a fake 7 day history, 40 runs of each test per day (runs pytest 280 times)
  • pip install -r requirements.txt and python generate_test_results.py
• Create 15 JUnit test reports
  • pip install -r requirements.txt and python generate_junit_history.py
