fix(router): cap the default OTPM reservation and reconcile token counters after each call (#49054)
* fix(router): cap the default OTPM reservation for requests without max_tokens

* fix(router): reconcile ITPM and OTPM reservations after every successful call

* fix(router): read the default OTPM reservation from the served model and make its fraction configurable

The default reservation now looks up max output from litellm_params.model, as main does, so a pricing base_model never changes it. NO_MAX_TOKENS_TPM_RESERVATION_FRACTION sets the fraction for both the router check and the key and team TPM floor. A max_tokens that is not a number or string counts as no cap instead of raising inside the check.

* fix(router): refund a failed attempt's io token reservation in make_call

The proxy passes one logging object to every retry, and it runs failure
callbacks only for the first attempt, so the last attempt's ITPM and
OTPM reservation stayed held until the minute ended. Each attempt that
raises now gives its reservation back before the retry or fallback

* fix(router): count Anthropic cache writes once in ITPM reconcile

Native /v1/messages usage reports input_tokens without cache reads and writes, so the reconcile now maps it through AnthropicConfig.calculate_usage before subtracting cached tokens.

* fix(router): use a deployment max_tokens, charge late usage to its finish minute, and read the reservation fraction as a fraction

* fix(router): reserve with the deployment cap only through the param the request's API sends

* fix(router): never let a deployment's output cap raise the reservation above the default

* test(router): move the reservation fraction env var test to the integration suite

The unit test started a child interpreter, which the unit guide forbids. The integration test boots a real proxy with the env var set and checks admission against the held reservation.

* test(router): retry the reservation fraction scenario when the minute rolls over

The OTPM counter is keyed by minute, so a rollover between the held stream and the capped requests gave the capped request a fresh counter. The control request now leaves room for usage the first attempt left in the new minute.

* test(router): give the rollover retry its own deployment

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/unit

This folder can only run mock tests.
