Tin Chi Lo 2e854dddb3 fix(router): drop a tier param the routed target cannot take
A complexity tier's litellm_params are an operator override applied to every request that tier
routes, and they were written into the request kwargs unconditionally. When the tier set a param
the target does not declare, get_optional_params raised UnsupportedParamsError before the request
left the proxy, so the whole tier answered 400. The bundled Lite preset sets reasoning_effort on
its complex tier, and four of the thirteen kimi-k3 map entries reject that param, so a router
built from a first-party template failed on every complex prompt

Filter the tier params at both store sites against what the group's deployments declare. The
candidate set is asked of the module that raises rather than derived from a second list, so
credentials, endpoint and transport controls are never at risk: base_url, timeout,
default_headers, organization and deployment_id are not chat completion params and never reach
that comparison. A param survives if any deployment could take it, since routing has not picked
one yet, and it survives an unresolvable provider or an empty group, since a best-effort filter
must not narrow what the request already did

The skip list _check_valid_arg applies before rejecting a param now has one owner both it and the
router read, so the two cannot drift

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.
