• Enable access to modern Python features including structural pattern matching, enhanced type hints, and improved error messages

Changes Made

📋 Detailed Changes (45 files affected)

CI/CD Infrastructure

• Updated GitHub Actions workflows (ci-release.yml, ci-staging.yml, ci-testing-deploy.yml) to use Python 3.10
• Modified Docker build matrices to target Python 3.10

Docker Infrastructure

• Updated all service Dockerfiles to use Python 3.10.12 base image
• Modified build arguments across all containerized components

Package Configuration

• Updated setup.py files across all packages and services to require >=3.10
• Modified Python version requirements in package metadata

Requirements & Documentation

• Updated requirements/PYTHON_VERSION from 3.9 to 3.10
• Updated Python upgrade documentation in requirements/how-to-upgrade-python.md

Affected Services & Packages

• All core services: api-server, catalog, director-v2, storage, web, etc.
• All supporting packages: models-library, service-library, settings-library, etc.
• All infrastructure components: migration, gateway-server, autoscaling, etc.

Motivation

Upgrading to Python 3.10 provides several key benefits:

1. Enhanced Developer Experience: Improved error messages with precise locations and helpful suggestions
2. Modern Language Features: Access to structural pattern matching (match/case), union type operators (|), and parenthesized context managers
3. Improved Type System: Better type hints with TypeGuard, ParamSpec, and explicit type aliases
4. Security & Performance: Updated OpenSSL requirements and runtime optimizations
5. Platform Currency: Maintaining compatibility with modern Python ecosystem and tooling

Python 3.10 Key Features

Python 3.10 introduces several powerful features that will benefit our codebase:

• 🔀 Structural Pattern Matching: New match/case statements for cleaner conditional logic
• 📝 Enhanced Type Hints: Union operator (int | str) and improved generic type support
• 🐛 Better Error Messages: More precise error locations and "Did you mean..." suggestions
• ⚡ Performance Improvements: Faster startup and runtime optimizations
• 🔒 Security Enhancements: Updated OpenSSL requirements and encoding warnings

📖 Official Release Notes: What's New in Python 3.10

Impact

• ✅ No Breaking Changes: This migration maintains backward compatibility
• 🚀 Enhanced Capabilities: Unlocks modern Python features for future development
• 🔧 Infrastructure Modernization: Updates all build and deployment pipelines
• 📦 Ecosystem Alignment: Ensures compatibility with current Python ecosystem

Test Plan

• All CI/CD workflows updated to use Python 3.10
• Docker images build successfully with new Python version
• Package requirements properly specify Python 3.10+ compatibility
• Full test suite execution on Python 3.10 runtime
• Deployment verification in staging environment
