The Puppet module contint has grown organically over the years and the manifests are rather messy. Something we found recently is that a slave has to include contint::packages::labs which in turns includes mediawiki::packages. They take a while to install which slow down disk image creation.

Ops requested Jenkins slaves to be pooled using Jessie, but some of the packages or manifests are not installable there.

The whole contint::packages and contint::packages::labs are just a big chunk of mess.

We need to split out the classes in reusable classes. That has been done for python already with contint::packages::python.

A low hanging fruit is doing the same for the ruby related packages which are needed for bundler and Selenium.
