From [[ https://www.mediawiki.org/wiki/Wikimedia_Release_Engineering_Team/Checkin_archive/20150721 | Releng checkin on 2015-07-21 ]], we should upgrade the puppet master on #beta-cluster to Trusty and a standalone instance. The current one has performances issues and collocated with the salt master.
> Puppet master: time to migrate to Trusty!
> Save cherry picked patches
> Delete instance, recreate one with same name (integration-puppetmaster), being bigger and running Trusty
> Run puppet on all instances via salt to request new cert
> Wait for puppet autosigner to kick in
> Profit \O/
