Subject: [PATCH] keep uvicorn idle connections open longer than nginx's
 upstream keepalive

uvicorn closed idle connections after its 5s default while nginx kept them pooled for 60s, so a request nginx sent on a connection uvicorn was closing got a 502. nginx retries that on a fresh connection for most methods, but not for POST or PATCH.
