In zh_CN version, install guide in Red Hat Enterprise Linux 7, CentOS 7, and Fedora 20 Kilo version----Install and configure controller node part

the install guide is base on kilo,but when sync the neutron database still use the 'juno' version, there will be cause error in the next steps.

# su -s /bin/sh -c "neutron-db-manage --config-file /etc/neutron/neutron.conf \
  --config-file /etc/neutron/plugins/ml2/ml2_conf.ini upgrade juno" neutron

the 'juno' should change to 'kilo'
