Comment 4 for bug 1552285

Hi Julien

The root cause of this problem is:
https://github.com/openstack/python-ceilometerclient/blob/master/ceilometerclient/common/utils.py#L131

The method textwrap.fill is different between python 3.4 and python 3.5. So the output has changed.

Maybe we need to judge the version of the python to determine what format of the output should be?

Thanks
