LiteLLM integration

[pjbedard]

Integrated LiteLLM into paios to facilitate the interaction with the LLMs of various providers using a standard interface.

• introduced Llm model
• introduced ModelsManager, that initializes and uses the LiteLLM router to interact with models from different providers (at present time, only Ollama and OpenAI models are loaded during the ModelsManager's initialization)
• implemented Llm-related API endpoints:
  • get-all
  • get
  • completion, which accepts the OpenAI-style parameters as well as provider-specific parameters
