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.

Tests that call host.backend.get_hostname() to switch on test
assertions are likely to fail open. Stop using this in zuul tests
and instead add new files for each of the types of zuul hosts
where we want to do additional verification.
Share the iptables related code between all the tests that perform
iptables checks.
Also, some extra merger test and some negative assertions are added.
Move multi-node-hosts-file to after set-hostname. multi-node-hosts-file
is designed to append, and set-hostname is designed to write.
When we write the gate version of the inventory, map the nodepool
private_ipv4 address as the public_v4 address of the inventory host
since that's what is written to /etc/hosts, and is therefore, in the
context of a gate job, the "public" address.
