I18N problem in Nova's test suites

[Jian Wen]

Some unit tests rely on HTTP response.
Like "self.assertIn("invalid state for '%(_action)s'" % locals(), res.body)" in
/opt/stack/nova/nova/tests/api/openstack/compute/contrib/test_admin_actions.py .
If the response was translated to other language like Chinese the assertion will fail.

How to reproduce the bug:
    % export LANG=zh_CN.UTF-8
    % export LANGUAGE=zh_CN:en_GB:en
    % export LC_MESSAGES="zh_CN.UTF-8"
    % ./run_tests.sh

Change locale to english would fix this:
    % export LANG=en_US.UTF-8
    % export LANGUAGE=en_US:en
    % export LC_ALL=C
    % ./run_tests.sh
