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. Closes-Bug: #1582288 Change-Id: I558ba329b7247cdfcf660e392c3ae0c4a0d65a53
