Zabbix checks item net.tcp.service[tcp,,11211] that doesn't work because memcached listen only address on br-mgmt

Zabbix tries to connect on 127.0.0.1
root@node-9:~# grep 11211 /var/log/zabbix/zabbix_agentd.log | head
 23696:20141029:104826.999 Requested [net.tcp.service[tcp,,11211]]

root@node-9:~# netstat -nl | grep 11211
tcp 0 0 192.168.0.3:11211 0.0.0.0:* LISTEN
udp 0 0 192.168.0.3:11211 0.0.0.0:*

So we need to change item to check specific IP address instead of 127.0.0.1
