fix i18n messages

[ZhiQiang Fan]

As some new feature is added, i18n support for message is broken **again**, for, i.e. https://github.com/openstack/neutron/blob/master/neutron/plugins/cisco/nexus/cisco_nexus_plugin_v2.py#L112 and there are more.

messages can be divided to 4 parts:
1) log message <-- important
2) exception message <-- important
3) print message <-- important
3) opt help message <-- need discussion

 i think all of them need i18n support, because these messages will be exposed to end-client-user/operators.

If neutron-drivers think this is invalid, then please change its status then i will stop.

As of Dec 2015, the help message looks correct.

  --peer-address PEER_ADDRESS
                        Peer gateway public IPv4/IPv6 address or FQDN.
  --peer-id PEER_ID Peer router identity for authentication. Can be
                        IPv4/IPv6 address, e-mail address, key id, or FQDN.
