Add directory resources to puppetdb module

I think that the puppetdb module expects the package to do this work,
and that's why it doesn't do this for us. There may also be an issue
with the puppetdb module setting up a config file under /etc and the
puppetdb application looking for a config file under /opt/puppetlabs
