v1 for AGS Spec Provider Class

[victordibia]

Create an initial provider class for mapping declarative specs to agentchat specifications. Ideally this will be refactored to use a generic provider at some future time. Core behaviour would be to take in a declarative (json/yaml) spec and return an AgentChat team that can run.

{
  "version": "1.0.0",
  "component_type": "team",
  "name": "weather_team",
  "participants": [
    {
      "component_type": "agent",
      "name": "writing_agent",
      "agent_type": "AssistantAgent",
      "system_message": "You are a helpful assistant. Solve tasks carefully. When done respond with TERMINATE",
      "model_client": {
        "component_type": "model",
        "model": "gpt-4o-2024-08-06",
        "model_type": "OpenAIChatCompletionClient"
      },
      "tools": [
        {
          "component_type": "tool",
          "name": "get_weather",
          "description": "Get the weather for a city",
          "content": "async def get_weather(city: str) -> str:\n    return f\"The weather in {city} is 73 degrees and Sunny.\"",
          "tool_type": "PythonFunction"
        }
      ]
    }
  ],
  "team_type": "RoundRobinGroupChat",
  "termination_condition": {
    "component_type": "termination",
    "termination_type": "CombinationTermination",
    "operator": "or",
    "conditions": [
      {
        "component_type": "termination",
        "termination_type": "TextMentionTermination",
        "text": "TERMINATE"
      },
      {
        "component_type": "termination",
        "termination_type": "MaxMessageTermination",
        "max_messages": 10
      }
    ]
  }
}
