374c3458d5 feat: add sagemaker_nova provider for Amazon Nova models on SageMaker (#21542)
* feat: add sagemaker_nova provider for Nova models on SageMaker

Add support for custom/fine-tuned Amazon Nova models (Nova Micro, Nova Lite,
Nova 2 Lite) deployed on SageMaker Inference real-time endpoints.

Nova uses OpenAI-compatible request/response format with additional
Nova-specific parameters (top_k, reasoning_effort, allowed_token_ids,
truncate_prompt_tokens) and requires stream:true in the request body.
Nova endpoints also reject 'model' in the request body.

Changes:
- New provider: sagemaker_nova/<endpoint-name>
- SagemakerNovaConfig inherits from SagemakerChatConfig
- Override transform_request to strip 'model' from request body
- Override supports_stream_param_in_request_body (True for Nova)
- Extend get_supported_openai_params with Nova-specific params
- Refactored SagemakerChatConfig to use custom_llm_provider param
  instead of hardcoded strings (backwards-compatible)
- Consolidated main.py routing for sagemaker_chat and sagemaker_nova
- 22 unit tests + 9 integration tests (skip-gated)
- Documentation with SDK, streaming, multimodal, and proxy examples
- All tests verified against live SageMaker Nova endpoint

* fix: move integration tests to tests/local_testing/ per test directory policy

* fix: remove unused module-level SagemakerNovaConfig instance

The sagemaker_nova_config singleton was never imported or used — the
ProviderConfigManager creates its own instance via the lambda registered
in utils.py. Removing this leftover boilerplate.

Testing for litellm/

This directory 1:1 maps the the litellm/ directory, and can only contain mocked tests.

The point of this is to:

  1. Increase test coverage of litellm/
  2. Make it easy for contributors to add tests for the litellm/ package and easily run tests without needing LLM API keys.
