Make nginx load balance using least-connections

By default, nginx uses round robin for load balancing. Round robin
works well when all requests take same amount of time, but is not
optimal for dynamic loads.

With least-connected load balancing, nginx will try not to overload
a busy server with excessive requests, sending requests to a less
busy server instead.
