Neutron Stadium i18n

• Refer to oslo_i18n documentation for the general mechanisms that should be used: http://docs.openstack.org/developer/oslo.i18n/usage.html
• Do NOT use the _i18n module in neutron-lib or neutron.
• It is recommended that you create a {package_name}/_i18n.py file in your repo, and use that. Your localization strings will also live in your repo.
• The neutron.i18n module will be around for a release or two, with shared localization strings, but migration is encouraged.
