This zuul02 instance will replace zuul01. There are a few items to
coordinate when doing an actual switch so we haven't removed zuul01 from
inventory here. In particular we need to update gearman server config
values in the zuul cluster and we need to save queues, shutdown zuul01,
then start zuul02's scheduler and restore queues there.
I believe landing this change is safe as we don't appear to start zuul
on new instances by default. Reviewers should double check this.
