fix(router): stop concurrent deployment deletes from crashing deployment lookups (#47680)
* fix(router): stop concurrent deployment deletes from crashing deployment lookups

delete_deployment and upsert_deployment shrink model_list before they repair
the index maps, so a lookup on another thread in that window read a stale
index: IndexError, or the neighbouring deployment and its credentials. An add
racing a delete could corrupt the index for good.

One RLock now covers model_list and the three index maps. Delete, upsert, add
and the set_model_list reset change them under it, and every lookup that turns
an index into a deployment reads under it.

Fixes #45242

* test(router): release the held delete when the read reaches the index lock

The race tests released the held write after a fixed 0.2 s, so a reader the runner
stalled past it read the repaired list and passed on unfixed code. The read now runs
on its own thread and the write stays held until the read returns or reaches the
router's index lock; the 10 s bound only fails a broken synchronization.

The integration test gains the audit cells: chat, streaming, Responses and
Anthropic messages calls (sync and async, by model name and team public name)
during a held delete, the same for upsert, add and set_model_list, a request for
the deployment being deleted, a provider error, a double delete, and thread and
async bursts during upsert churn.

* test(router): cover the early return of a delete and the team filter of get_model_ids

delete_deployment now returns None from inside the index lock, and get_model_ids by
name reads its deployments through _deployments_named; pin both: deleting an unknown
id returns None and leaves the list alone, and exclude_team_models drops only the
team deployment.

* fix(router): read deployments by name under the index lock outside the Router

The response polling provider check, the complexity router's adaptive pool and the
savings baseline turned the name index into list positions themselves, so a concurrent
delete could still hand them a stale slot. They now read through Router.deployments_named,
which takes the deployment index lock.

* fix(router): type the locked deployment lookups as DeploymentTypedDict

deployments_named and _team_deployments_named returned tuple[Any, ...]. They now return
DeploymentTypedDict rows, which is what model_list holds. The adaptive pool setup in the
Router and the complexity router drop their branches for pydantic Deployment rows, which
these lookups never return, and should_include_deployment accepts the typed row.

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.
