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
ironic-inspector/locale/ironic-inspector.pot to
ironic_inspector/locale/ironic_inspector.pot. For this we need to update
setup.cfg. Also fix some errors for translation setup in setup.cfg
Update also domain name in i18n.py.
The project has no translations currently, let's remove the outdated
pot file, the updated scripts work without them. So, we can just
delete the file and once there are translations, an updated pot file
together with translations can be imported automatically.
