Detailed bug description:
 By default, the following package is installed for Horizon when deploying MOS9 w/ Mitaka on Ubuntu+UCA 14.04.

# dpkg -l | grep horizon
ii python-django-horizon 2:9.1.0-0ubuntu1~cloud0 all Django module providing web based interaction with OpenStack

This causes Horizon to render its UI improperly (e.g. it appears as if the CSS/JS isn't loaded).

Steps to reproduce:
 - Deploy Mirantis OpenStack 9.0 w/ Mitaka on Ubuntu+UCA 14.04.
 - Access Horizon, and you will see that it appears to be "broken".
Expected results:
 The package that should be installed is python-django-horizon_9.0.1-2~u14.04+mos22_all.deb or the installed package should be compatible w/ other MOS packages.
Actual result:
 python-django-horizon_9.1.0-0ubuntu1~cloud0_all.deb is installed, causing the UI to break.
Reproducibility:
 - This occurs on every deployment w/ the UCA option selected.
Workaround:
 - Set the UCA repository to a lower priority than that of the MOS repos, in order to install the appropriate python-django-horizon package.
Impact:
 Horizon becomes difficult to utilize, none of the CSS appears to be loaded.
Description of the environment:
- Operation system: Ubuntu 14.04.5 LTS
- Versions of components: Mirantis OpenStack 9.0
- Reference architecture: 1 controller, 2 compute (3 nodes) on KVM.
- Network model: Neutron with VLAN segmentation
