fix(router)!: count an explicit allowed_fails of 3 and keep fallback deployments out of cooldown (#46183)
* fix(router): count an explicit allowed_fails equal to the default as set

Router(allowed_fails=3) stored the same value as an unset Router, so
_is_allowed_fails_set_on_router treated it as "not set" and kept the
rate-based cooldown logic. Keep the passed value in explicit_allowed_fails,
like _explicit_timeout, and count it as set.

* chore(router): drop the comment on explicit_allowed_fails

* fix(router): keep the fallback deployment out of cooldown when no deployment can be picked

When every deployment of the requested model is in cooldown, the router raises
"No deployments available" and schedules the failure callbacks on the request's
logging object. By the time they run, the fallback has already written its own
deployment into that object, so the 429 counted as a failure of the healthy
fallback deployment and cooled it down too, leaving the model group with nothing
to serve.

Tag the selection error and skip cooldown accounting for it, the same way
advisor orchestration failures are skipped.

* test(router): annotate the new cooldown test variables with Final

* test(router): pin that a saved allowed_fails of 3 stays unset and type the fallback helper

* test(router): use a fixed start time in the fallback helper

* test(router): cover a fallback group staying up after the primary's selection fails

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.
