Previously, there was a 'ruby_packages' dictionary that mapped the
ruby version (1.8, 1.9, 1.9.1) to a list of packages that would need
to be installed to get a functional gems.
This replaces that with a method that is more likely to support future
versions without requiring updates to cloud-init.
It is not identical output as before. The changes are:
* do not include 'ruby' in the case of 1.8, but rather 'ruby1.8'
This is because the default could change, and 'ruby' would depend
on a different default version.
* do not explicitly list 'libruby-<version>' as that is a dependenency
of 'ruby<version>'
* End result is for any 'version' != 1.8, you'll get the following installed
ruby<version>
ruby<version>-dev
