SwiftWinds 583bdd34a2 fix(bedrock): allowlist Bedrock Invoke body fields and filter all anthropic-beta values
Two fail-safes for the /v1/messages → Bedrock Invoke pass-through so new
Anthropic-only extensions Claude Code starts sending can't reach Bedrock
and trigger a 400 "Extra inputs are not permitted":

1. Top-level body fields are filtered to a typed allowlist. New
   `BedrockInvokeAnthropicMessagesRequest` TypedDict (in
   `litellm/types/llms/bedrock.py`) captures the Bedrock Invoke Anthropic
   Messages body schema; the runtime allowlist is derived from its
   `__annotations__` so the type and the filter can't drift. Anchored to
   the AWS reference page in docstrings + transform comment. An
   exact-set test pins the resolved allowlist so any future edit forces
   conscious review.

   Drops context_management, output_config, speed, mcp_servers,
   container, inference_geo, internal litellm_metadata, and any future
   Anthropic addition. output_format stays as an active inline-schema
   conversion (not just a strip).

2. The anthropic-beta header list is filtered + transformed against the
   bedrock mapping for ALL betas, not just auto-injected ones. The
   previous code union'd user-provided betas back in unfiltered, so a
   client on a new Anthropic-direct beta (e.g. advisor-tool-…,
   context-management-…) could still pin the request to fail. In a proxy
   context the client can't know the backend is Bedrock; the provider
   mapping is authoritative. User-provided drops are logged at WARNING
   so intentional overrides leave a breadcrumb.

Updates one existing test that happened to assert on the old buggy
pass-through (it used output-128k-2025-02-19, which is null in the
bedrock mapping and would 400 at runtime); rewrote it against a
bedrock-supported beta.

Scope: messages/invoke only. The same user-beta bypass exists in
chat/invoke but that's a different code path with different
user-expectation trade-offs — follow-up.

In total litellm runs 1000+ tests

[02/20/2025] Update:

To make it easier to contribute and map what behavior is tested,

we've started mapping the litellm directory in tests/test_litellm

This folder can only run mock tests.
