Horizon static content not set correctly in vhost

[Ben Ramsey]

Detailed bug description:
After completing a deployment of OpenStack Ocata with Fuel 11.0 the contents of the Horizon dashboard are mostly missing. From investigation of the loading of the dashboard it was found that 404 errors were occurring for most of the static content of the page i.e. css, js, and images.

Steps to reproduce:
Deploy OpenStack Ocata with Fuel 11 and go to the dashboard once completed

Expected results:
The dashboard is correctly laid out, with no missing content

Actual results:
Majority of static content unable to be found by the browser

Reproducibility:
Consistent even after restarting apache2

Workaround:
In the /etc/apache2/sites-enabled/horizon_vhost.conf change the Alias static line to be:
Alias /horizon/static /var/lib/openstack-dashboard/static

Impact:
Dashboard usability significantly reduced with some features unable to be used e.g. Network Topology

Description of Environment:
/etc/fuel_build_id: 561
/etc/fuel_openstack_version: ocata-11.0
