Apache config results in no CSS loading

[Gregory Orange]

Detailed bug description:
Using Fuel 11 to deploy OpenStack Ocata UCA, the Apache configuration on the controller node results in no CSS loading in Horizon. Here's a sample access_log error:

192.102.250.216 - - 14/Mar/2017:07:53:41.783 "GET /horizon/static/dashboard/css/34f8a8f8d5e5.css HTTP/1.1" 404 243 168 "http://146.118.112.23/horizon/auth/login/?next=/horizon/identity/" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10.12; rv:51.0) Gecko/20100101 Firefox/51.0"

We noticed that /etc/apache2/sites-available/horizon_vhost.conf has:
  Alias /horizon/static "/usr/share/openstack-dashboard/static"

This directory doesn't exit, but the correct files appeared to be in /var/lib instead of /usr/share. We changed it to that, and CSS loads much better.

Steps to reproduce:
Using Fuel 11, install OpenStack Ocata UCA. Browse to the resulting Horizon interface.

Expected results:
Correctly loading CSS.

Actual result:
No CSS, text only.

Reproducibility:
Always.

Workaround:
Change /etc/apache2/sites-available/horizon_vhost.conf so that the /horizon/static Alias points to /var/lib... instead of /usr/share...

Impact:
Difficult to use web interface.

Description of the environment:
 Operation system: Controller node: Ubuntu 16.04.2 LTS. Fuel: Centos 7.
 Versions of components: Fuel 11, OpenStack Ocata.
