yatin d3d27d7ea8 Use hiera interpolation for memcached_network
After [1] iptables rules are not set for memcached service
thus services relying on memcached were not functioning well.
With [2] it's requrired to use hiera interpolation for service
configs, this patch fixes it for memcached_network.

opening memcached to external network can be dangerous.
