This places the puppet web dashboard puppetboard from
https://github.com/nedap/puppetboard onto the puppetdb server.
This enables anyone to see the output of puppet runs, which nodes
are failing and which nodes have not checked in over time. We can
also quickly and interactively query the facts database.
This also modifies install_modules.sh to support a list of modules
that will be installed without dependency resolution.
