Puppet OID listing should be shareable between Clojure and Ruby code

We currently share a copypasta list of OID -> shortname translations for puppet's OID arcs between ruby code (oids.rb in puppet) and clojure (certificate_authority.clj in puppet server).

We should be storing that static mapping in a file on disk that can be read by either codebase. We already do this with the csr_attributes.yml file, but only for user-defined extensions above what we hardcode.

This will require changes in both puppet and puppetserver.
