fix(proxy): cooldown errors carry 429, Sentry starts at boot without request bodies, tracing failures log at ERROR, exporter counters exported (#46344)
* fix(router): carry a 429 status on cooldown and no-deployment errors

RouterRateLimitError and RouterRateLimitErrorBasic had no status_code, so the
proxy answered an all-deployments-cooled-down request as a generic 500 class
error and logged the bug report notice for every cooldown. Both now carry
status_code 429, which the proxy maps to a rate_limit_error and which the
retry policy already treats as retryable

* fix(proxy): start Sentry at config load and never attach request bodies

Sentry only came up inside set_callbacks on the first LLM call, so boot and
background errors were never reported, and general_settings.alerting: [sentry]
always raised Missing SENTRY_DSN because the alerting path read a dead
litellm.utils pin instead of the live SDK. The proxy now initializes Sentry
once while loading the config whenever sentry is a configured callback or
alerting target, the alerting and failure handlers read the live instance, and
max_request_body_size is pinned to never so prompts and completions stay out
of Sentry events

* fix(tracing): log Lens failures at ERROR and export row counters to Prometheus

A tracing store that fails to start, or a Lens service that rejects a batch,
was only logged at WARNING, so operators running at the default ERROR level
never saw tracing silently go dark. Both now log at ERROR and name the lens
store. The exporter's rows_written and rows_dropped tallies were never
exported, so the two counts are now Prometheus counters
litellm_lens_export_rows_written_total and
litellm_lens_export_rows_dropped_total, registered lazily on the default
registry like the other proxy-level counters and charted on the all-metrics
Grafana dashboard

* test(proxy): drop the litellm import the alerting tests no longer use

* fix(proxy): start Sentry once a DSN is set, from any config source

Boot-time init used to lock Sentry in even with no SENTRY_DSN, so a DSN loaded later from DB environment_variables was never picked up. initialize_sentry now skips when no DSN is set and re-inits when the DSN changes. alerting_handler calls it too, so alerting: [sentry] set through the DB works. Drops the litellm_settings.callbacks check since that config fails to load with sentry in it

* fix(sentry): keep stack frame locals out of events unless PII is opted in

Frame locals carried prompts (messages, request bodies, provider options) into every error event. include_local_variables now follows SENTRY_SEND_DEFAULT_PII

* test(router): drop the test that only pinned the 429 class attribute

* fix(proxy): start Sentry at boot when it is only an input callback

* fix(proxy): keep Sentry init and alerting within the strict ruff and basedpyright ceilings

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.
