Puppet the puppetmaster apache vhost

We need to slightly tweak the puppetmaster-passenger package's apache
vhost file slightly for our environment. First we need to set a max
requiests limit for passenger processes so that they are cycled out in
order to avoid a memory leak. Second we enforce TLS and no SSL to
prevent POODLE.
