[Infra] Speed up proxy unit tests by replacing litellm reload with state snapshot 
tests/proxy_unit_tests/conftest.py was calling importlib.reload(litellm) in an
autouse function-scoped fixture, which cost ~17s per test because it re-ran
the full litellm __init__ import chain. With 400+ proxy unit tests, this was
the single biggest driver of CI wall time — 18 of the top 20 slowest durations
in a typical run were just the 17s fixture setup.

Replace the reload with a snapshot-and-restore approach: snapshot the mutable
lists/dicts/sets on litellm and litellm.proxy.proxy_server once at conftest
import, then deep-copy that snapshot back before each test. Callback lists,
caches, router state, etc. still get reset between tests, but the expensive
import chain only runs once per worker.

Local measurement on test_proxy_utils.py: 188 tests in 3.50s (previously took
~15 minutes of CI wall time on a single worker).

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.
