Upstream: do not unnecessarily create per-request upstreams. If proxy_pass (and friends) with variables evaluates an upstream specified with literal address, nginx always created a per-request upstream. Now, if there's a matching upstream specified in the configuration (either implicit or explicit), it will be used instead.
