Open Stack

Hi,

In our internal CI system we realized that stable/kilo devstack fails 
with the following stack trace:
2016-04-18 13:11:30.344 | + /usr/local/bin/*keystone-manage db_sync*
2016-04-18 13:11:31.142 | Traceback (most recent call last):

0.11.1 (/usr/local/lib/python2.7/dist-packages), 
Requirement.parse('pbr>=1.8'), set(['testresources']))*

It seems that the root cause is that testresources has a new version 
2.0.0 from 18 April.

I tried to find similar errors on openstack infra, but for me 
http://logstash.openstack.org/ gives back no result.

I have a patch in requirements (https://review.openstack.org/307174) but 
I got the same error for those runs.

Could somebody help to find a solution for this?

Regards
Lajos
