Bjoern Teipel 045b2d8f54 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
