feat: Use AI Agent in SQL Kernel function

[Pavan-Microsoft]

Purpose

This pull request introduces several enhancements and refactors to the Azure AI agent architecture, including the addition of a new SQL agent factory, improvements to configuration management, and updates to deployment templates. These changes aim to improve modularity, scalability, and support for additional AI agent types.

Infrastructure Updates:

• Added a new azureAiAgentApiVersion parameter (2025-05-01) to infra/main.bicep and corresponding updates in infra/main.json to propagate this version throughout the deployment pipeline. This includes environment variable definitions and output parameters. [1] [2] [3] [4] [5] [6] [7]

Agent Factory Refactoring:

• Introduced a new BaseAgentFactory abstract class to standardize the creation and management of agent instances using a singleton pattern.
• Refactored ConversationAgentFactory and SearchAgentFactory to extend BaseAgentFactory for better code reuse and consistency. [1] [2] [3]

New SQL Agent Factory:

• Added SQLAgentFactory to create and manage SQL agents for generating T-SQL queries based on user instructions and predefined schemas. This factory integrates with the Azure AI Project API.
• Updated app.py to initialize and manage the lifecycle of the new SQL agent within the FastAPI application. [1] [2]

Configuration Enhancements:

• Added a new ai_project_api_version configuration parameter to the Config class, enabling flexibility in specifying the Azure AI Project API version.

Plugin Updates:

• Updated ChatWithDataPlugin to integrate with the new SQLAgentFactory, enabling SQL-based interactions within the chat plugin.

Does this introduce a breaking change?

• Yes
• No

Golden Path Validation

• I have tested the primary workflows (the "golden path") to ensure they function correctly without errors.

Deployment Validation

• I have validated the deployment process successfully and all services are running as expected with this change.
