add redhat vhost

By default, the apache module purges all vhosts
that were not explicitly specified by puppet.

This causes the horizon vhosts to be purged b/c they
are created as a part of the pacakge installation.

This commit adds a file resource that represents the horizon
vhost to prevent it from being deleted.
