stable\kilo is broken due to version conflict error

[Kairat Kushaev]

When I try to propose some changes for review the tests are failing because of VersionConflict error.
See:
http://logs.openstack.org/09/187909/1/check/gate-heat-python27/78b4bc5/console.html
I tried to recheck but it fails with the same error, so it seems that we introduced some conflict dependencies in stable/kilo.

Here is part of the log:

I would recommend backporting https://review.openstack.org/#/c/185287/

[Kairat Kushaev (kkushaev)]

I proposed the review above for backport here:
https://review.openstack.org/#/c/188330/
cause don't see any other reviews about it.

[Kairat Kushaev (kkushaev)]

Closing because backport is merged and issue was fixed.
