* get rid of the --use_lockout flag since it will be specified in paste config (Example line is commented out in etc/nova-api.conf, factory is in place) * remove old nova-api binary and promote nova-api-paste * change how we store ec2 parameters to bin the the ApiRequest * get rid of Router, since paste.urlmap is equally effective (Requestify now gets passed the name of the controller requests are to.)
