Switch over to phusion baseimage. Prevent everything from daemonizing and start it with runit under phusion. Make workers trap and handle sigint and sigterm. Extend the reservation to 1hr for dockerfilebuild. Update nginx to remove the dependency on libgd. Merge the requirements and requirements enterprise files.
