Fixes bug 1103519
Following http://wiki.openstack.org/Translations to integrate transifex
translation into quantum
We added the empty file quantum/locale/quantum.pot to avoid the
failure of the Jenkin's translation-jobs because git doesn't allow empty
directory to be added into the repository.
After this patch accepted, we need to do as below:
1. Make the transifex quantum project
(https://www.transifex.com/projects/p/quantum/) as part of the
openstack transifex project hub and give access to the transifex
openstack Jenkins account.
2. Add the translation-jobs into openstack/openstack-ci-puppet for
ceilometer.
