Comment 1 for bug 1313731

This issue also related to tuskarclient, because (as we can see in traceback) error from pythonclient hides the original exception.

Seems to be, that this error in pythonclient is appeared after the patch https://review.openstack.org/#/c/87315/ (Revert "Use HTTPClient from common apiclient code") was merged. So now tuskarclient use `httplib` library (instead or `request`) for http request. But from_response() method from tuskarclient/openstack/common/apiclient/exceptions.py file works correctly, when we put there response from `requests` library.
