    Configure nofile OS limit for memcached server role

    This fix adds 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.
