I18n team has an exceptional project name "I18n". http://git.openstack.org/cgit/openstack/governance/tree/reference/projects.yaml#n937 It brings unintended capitalization "I18N" with Python title() method. I18n is an abbreviation of internationalization, so we should use the name "I18n". Change-Id: Ibac3a78dbcb6bd5da9234c9fc39f6020b4e24c05
