Open Stack

Hi sahara cores,

As you might know Sahara has been broken for quite some time now due
to multiple reasons, and didn't have passing tests for Zed release at
all.

I have come up with a patch [1] that fixes major issues, including:
* Zuul Queus definition
* Adapting new jsonschema version
* Replacing usage of iteritems with six

As a result Zuul is happy, all tempest and tox tests are passing it
the moment. It would be great if you could review these changes and
land other important patches to unblock other contributors in the
project and prevent it from falling under "inactive" projects list.
