A different approach to apache::mod::passenger

Note: this requires
huit/puppetlabs-apache@034d018b562e1dce3f6aea4018ba085a0800b03c to be
merged upstream before it will work!  Clone from huit/puppetlabs-apache
mod_libdir_package_params branch.
Merge branch 'puppetlabs_apache' into cloudlet-railsapp
