We should update the RESTBase test cluster in Beta Cluster so that it can be used for VE and other testing. We should also set up a mechanism to automatically keep this cluster updated with the latest restbase master.
[x] Set up the VM instances in deployment-prep and hook them up with puppet/salt
[x] Figure out a way to add the beta cluster wiki domains into `config.yaml`
[ ] Modify ops/puppet so that the Cassandra and RESTBase roles work in both production and beta cluster
[ ] Configure and activate the RestBaseUpdateJobs extension and integrate RB with VE
[ ] Figure out a way to update code in the beta cluster so that we can test stuff before releasing it into production
