Follow new infra setup for translations, see spec http://specs.openstack.org/openstack-infra/infra-specs/specs/translation_setup.html for full details. This basically renames oslo.concurrency/locale/oslo.concurrency.pot to oslo_concurrency/locale/oslo_concurrency.pot. For this we need to update setup.cfg. Update also domain name in i18n.py.
