test(e2e): event_loop_stalls perf case fails on a gateway event-loop hold over 100 ms that is not on its allowlist (#46974)
* test(e2e): event_loop_stalls perf case reads the gateway's asyncio debug log and fails on a loop hold over 100 ms that is not on its allowlist

The gateway runs the stdlib loop in debug mode (new LITELLM_EVENT_LOOP=asyncio knob next to
PYTHONASYNCIODEBUG=1), the case replays the mixed body mix at 1 rps and groups asyncio's
'Executing <Task ...> took X seconds' lines by coroutine and location. Known holds are listed with
the count they show today; anything else, or a known one past its count, fails the case. Opt-in
through E2E_PERF_EVENT_LOOP=1 so the nightly build skips it

* test(e2e): event_loop_stalls reads the pod list and pod logs through e2e_http instead of a raw httpx client

* test(e2e): event_loop_stalls charges a hold to garbage collection when the gateway's debug-mode gc log accounts for it

The proxy registers a gc.callbacks hook only when the event loop runs in debug mode and logs every
collection over the loop's slow-callback threshold (generation, collected count, seconds). The case
parser pairs such a pass with the hold line that follows it and reports the hold under a bounded
garbage collection bucket instead of the task asyncio happened to blame, which made 7 of 10 local
runs fail on a different task name each time. Holds the collector does not account for keep the
strict allowlist, which gains the prisma first-query warm-up and the second pub/sub subscriber

* test(e2e): event_loop_stalls allowlist caps set at twice the ten-run maximum
