[.Net] feature: Ollama integration

[iddelacruz]

Pull Request Summary:

This pull request introduces the integration of the Ollama API into our AutoGen system. The goal of this integration is to leverage Ollama's advanced AI capabilities to enhance our AutoGen's functionality, providing more accurate and context-aware content generation.

Key Changes:

Ollama Agent Implementation:

• Implemented OllamaAgent which handles communication between AutoGen and the Ollama API. This agent is responsible for sending requests to and receiving responses from the Ollama API.

Ollama Embeddings implementation:

• Implemented OllamaTextembeddingService to be able to generate text embeddings

Middleware Updates:

• Added OllamaMessageConnector as middleware to manage the data flow and transformations necessary for integrating responses from the Ollama API into the AutoGen workflow.

Configuration Management:

• Updated our configuration settings to include necessary parameters for the Ollama API, such as API keys, endpoint URLs, and default request options.

Error Handling and Logging:

• Enhanced error handling to manage potential API request failures and implemented detailed logging for debugging and monitoring the API interactions.

Unit and Integration Tests:

• Added comprehensive tests to ensure the reliability of the API integration. These tests cover various scenarios, including API response handling, error management, and system resilience under load.

Impact:

• Enhanced Capability: By integrating the Ollama API, AutoGen will significantly improve in delivering contextually relevant and precisely tailored content outputs.
• Increased Efficiency: Automated workflows will see a reduction in manual interventions and quicker turnaround times for content generation.
• Scalability and Maintenance: The integration is designed with scalability in mind, ensuring that as AutoGen's usage grows, the system remains robust and maintainable.

#2319

Next Steps:

• Review the integration setup and test results.
• Merge the PR after team approval.
  Monitor the system for any unexpected behaviors post-integration.
  Request for Review:
  I would appreciate feedback on the current implementation, especially concerning the error handling and data transformation logic. Please focus on the robustness of the integration and the clarity of the new configurations.
