features:
- The openstack-ansible-memcached_server role includes
a new override, ``memcached_connections`` which is
automatically calculated from the number of memcached
connection limit plus additional 1k to configure
the OS nofile limit. Without proper nofile limit
configuration, memcached will crash in order to support
higher parallel connection TCP/Memcache counts.
