Modularized StoryBoard Module

In order to get the puppet module for storyboard up to a level where
we can publish it to puppetforge, I did some work on it to create
separate modules which can be used by anyone to install storyboard.

- API and Webclient are now installed via storyboard::application,
  which assumes that you can provide the DB connection criteria.
- storyboard::cert is now a separate class, which accepts either
  files or strings, which generates the SSL certificate and chain
  files for storyboard.
- storyboard::params is our dependency checker.
- storyboard::init will install a standalone, entirely
  self-contained instance of storyboard.
- Added various puppet module files necessary for eventual
  deployment to puppetforge.
- Added README.md documentation for later puppetforge addition.

This patch also includes a new module: example42-puppi, which is a
series of convenience utilities useful for deployment. For example,
puppi::netinstall (used here) will fetch tarballs and zip files and
extract them into a provided directory. It also contains changes to
the storyboard configuration for the new refresh token support patch
in #94363
