Horizon: Install the openstack_dashboard django project in /var/lib/horizon

With this patch we avoid some problems:
- Horizon trying to write in /usr/lib/python2.7/site-packages/static
- We won't have to maintain a copy of local_settings.py
- The workaround of creating a symlink for django.wsgi is not needed
  now.

This patch also changes apache-horizon.conf to
- Change the path of django.wsgi file
- Load the horizon server with the url 'http://<IP-of-OpenStack>' (the
  'horizon/' suffix is removed)
- Grant permissions to access to /var/lib/horizon/static

Also changes 'tempest.conf' to change Horizon urls.
