Enable python-horizon to run from apache.

- modify python-horizon to install files needed for horizon/apache
- add apache configuration file (openstack-dashboard-apache.conf) to setup a
  virtual host running from port 80 to run the mod_wsgi/openstack-dashboard app
- add horizon-apache and apache2 to controller task list
- Note: local_settings.py differs from the one in examples in two ways:
  1. LOCAL_PATH = "/usr/share/openstack-dashboard/openstack_dashboard/static"

     since the apache app runs as daemon, we neeed to specify a path where
     daemon has write permissions
  2. configure python-horizon/apache to use memcached. (see CACHES)
