MAJOR UPGRADE - LangChain/OpenAI libraries.

[lvalics]

• Incorporate 'Ollama' into your example.env configuration and make sure to reflect these changes in your .env file for compatibility.
• We've expanded the logging capabilities within settings.py by deploying logging.debug for more detailed insights, although it remains inactive when the DEBUG mode is off.
• We've refreshed the dependencies listed in requirements.txt to ensure the latest support and functionality.
• Updates to LangChain and OpenAI libraries, now feature the exciting addition of Ollama, currently under development.
• This version has a significant update that is still pending comprehensive testing; therefore, we advise against deploying it in production environments until it is fully vetted.
• Modifications have been made to the history module to append the input message to requests sent to OpenAI. These changes are still being tested. (disabled for the moemnt)
