Title: Warn on unsupported node deployments

Added changes to node_layout.rb to warn users if they attempt to start AppScale with a deployment strategy other than the ones we regularly test. As part of this, we now enable users to separate ZooKeeper from the database master, and ZooKeeper from the 'master' node, which now only runs the load balancer and shadow roles.
