Currently, Keystone-Client is using 'memcache_servers' config option to store the memcache server info, while in OSLO project, it is using 'memcached_servers' to config the same option. It is better to change keystone-client's 'memcache_servers' to 'memcached_servers' to keep consistent between these two projects.
