fix(http_handler): keep a handler alive while its responses are still streaming
Closing an httpx client tears down the connection pool every response from that
client is streaming through. litellm caches HTTP handlers for one hour, and
nothing in a streaming response's reference graph points back at the handler --
httpx binds the response to the transport stream and the pool, never to the
client's wrapper. So when the cache entry expires, the handler's last reference
goes with it while its responses are still being read, GC runs `__del__`, and
every in-flight body on that pool is cut. The clock is per process and anchored
at first client construction, which is why the failures arrive in hourly bursts.

Rather than guard the finalizer, make it unreachable while the client is in use.
`create_client` installs one httpx `response` event hook that stamps the owning
handler onto `response.extensions`, so a response keeps its handler alive; the
handler is collected once its last response is gone and the existing `__del__`
then closes the client exactly as it does today. Both `__del__` bodies are
unchanged -- only the timing moves, so the disposal path cannot regress.

The hook closes over a weak reference to the handler, never a strong one: a
strong one would make the handler immortal and its client would never be closed
at all. There is a test for that specific invariant.

This reaches the paths a fix in `post()` cannot: the proxy passthrough routes
take `.client` off the handler and stream from the raw client, so the handler is
a function local that dies on return. An event hook on the client still sees
those responses.

Everything used is public httpx surface -- the `event_hooks` setter and
`Response.extensions`. That matters because litellm's default transport is
aiohttp, whose connector exposes no public way to ask whether a connection is in
use, so a fix built on httpcore's pool would pass under
DISABLE_AIOHTTP_TRANSPORT=true and silently do nothing by default. The
regression test is parameterized over both transports.

The sync twin in `HTTPHandler` has the same defect and gets the same treatment.

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.
