Pull Request Overview

This PR refactors the TDNF Package Manager implementation by extracting Azure Linux specific functionality into a separate class while keeping the base TDNF functionality abstracted. The goal is to create a cleaner architecture that separates the generic TDNF functionality from Azure Linux specializations.

Key changes:

• Refactors TdnfPackageManager to be an abstract base class with common TDNF functionality
• Creates new AzL3TdnfPackageManager class containing Azure Linux specific implementations
• Updates test class names and structure to match the new architecture
