This PR attempts to create shared base classes for tracing streams in our LLMObs integrations. The Anthropic, Gemini, Langchain, LiteLLM, Open AI / Azure Open AI, and Vertex AI integrations were all refactored to use this new standardized interface.

How it works

To create a traced stream, each integration should implement a sync (and async if needed) StreamHandler which contains the logic for initializing chunk storage, processing chunks, handling exceptions, and finalizing the stream.

This stream handler along with the actual object to be wrapped are passed into make_traced_stream or make_traced_async_stream which creates a traced stream from the object. Because some streaming objects are generators themselves while others are classes, these factory functions determine the appropriate class with which to wrap the object (_ClassTracedStream, _ClassTracedAsyncStream, _GeneratorTracedStream, or _AsyncGeneratorTracedStream).

The traced stream class is responsible for consuming the original streaming object and delegating tracing tasks to the stream handler.

TODO:

[ ] add documentation to base_stream_handler.py for directions on how to use the shared base classes
[ ] implement base classes for Bedrock Converse
[ ] implement base classes for Open AI responses
