Add parameter validation and integration tests with CI integration

[tarunramsinghani]

Summary

Adds comprehensive integration tests for TFX CLI with parameter validation and CI pipeline integration.

⚠️ Breaking Change

Parameter Validation: Unknown arguments now trigger errors instead of being silently ignored.

• Before: tfx build --invalid-arg → silently ignored
• After: tfx build --invalid-arg → shows error + help

Key Changes

• 🧪 Integration Tests: Extension creation, build task validation, CLI argument processing
• 🔧 Parameter Validation: Strict argument validation with helpful error messages
• 🚀 CI Integration: Automated test execution with xUnit result publishing
• 📁 Test Samples: Extension samples for comprehensive testing scenarios

Files Changed

• app/lib/tfcommand.ts - Added parameter validation logic
• tests/ - New integration test suites and sample extensions
• .azure-pipelines/common-steps.yml - Added CI test execution
• package.json - Added test:ci script
• tsconfig.json - Test compilation configuration

Migration Required

Review and fix any scripts using invalid TFX CLI arguments - they will now fail with clear error messages.

Testing

• 150+ integration tests covering CLI, extensions, and build tasks
• Automated CI execution with test result publishing
• Comprehensive test pipeline success - https://canarytestpf.visualstudio.com/canarytestspf/_build/results?buildId=291&view=results
• Tests all 3 OS with Node 16 and Node 20.
