Update translation setup

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.i18n/locale/oslo.i18n.pot to
oslo_i18n/locale/oslo_i18n.pot.
For this we need to update setup.cfg.

Update also domain name in _i18n.py.

Update unit test to adapt to domain name change.
