parse litellm attributes (#171)

[dinmukhamedm]

Important

Enhance Span class to parse and handle new LiteLLM attributes for input and output in spans.rs.

• Behavior:
  • Updated Span class in spans.rs to parse new LiteLLM attributes SpanAttributes.LLM_PROMPTS and SpanAttributes.LLM_COMPLETIONS.
  • Modified input_chat_messages_from_prompt_content() and output_from_completion_content() to handle new attribute prefixes.
  • Updated should_keep_attribute() to exclude LiteLLM attributes from being stored redundantly.
• Functions:
  • Added tool_call_attribute() to generate attribute keys for tool calls.
  • Updated output_from_completion_content() to handle tool call attributes with or without index.
• Misc:
  • Fixed typo in comment in spans.rs.

  The regex pattern is compiled every time the function is called, which is inefficient. It should be compiled once and reused.
