This commit updates the Puppetfile example module versions to list the
latest releases for the example modules as of 2019-07-10, and also
updates several files for style.
Standardizing on double-quotes in YAML due to:
1. Functional irrelevance between single vs. double quotes in our YAML
2. Prevalent use of double-quotes in Puppet documentation
3. Similar look-and-feel to other data serialization formats like JSON
This commit enables the control repo to use Hiera 5 environment-level
hiera hierarchy. This means adding a hiera.yaml to the repo, and moving
hieradata/ => data/.
We should do this to the control-repo template new customers base off of
because in a Hiera 5 world, the global hiera.yaml should be very minimal
(possibly even ONLY having the console level), and everything else
(nodes, common) belongs in the environment hiera.yaml.
This control-repo template is how people start using Puppet. It should
reflect using our most modern technologies.
