WSGI mod due wrong oslo i18n import

[Lucas Alvares Gomes]

When trying to start the Ironic API with apache wsgi mode I get

[Wed Jul 29 14:40:42.693332 2015] [:error] [pid 4317:tid 139835470763776] [remote 192.168.122.156:40449] mod_wsgi (pid=4317): Target WSGI script '/opt/stack/ironic/ironic/api/app.wsgi' cannot be loaded as Python module.

This is due the import at ironic/ironic/api/app.wsgi which is doing:

from oslo import i18n

It should be

import oslo_i18n as i18n

    Fix apache wsgi import

    The Oslo libraries have moved all of their code out of the 'oslo'
    namespace package into per-library packages. Seems we did forget the
    wsgi file.
