Use same indentation in doc/source/usage

The first code example for "Creating an Integration Module"
(http://docs.openstack.org/developer/oslo.i18n/usage.html) is not
rendered correctly, it is because the wrong indentation.

This patch corrects this mistake, and uses a same indentation in cross
of the whole file.

Universal is used to identify pure-Python module(by bdist_wheel). For
these, it is sufficient to build a wheel with _any_ Python ABI version
and publish that to PyPI (by whatever means).
