It looks like you are trying to run with two etcd instances. etcd requires
either one instance, or three or more. You can see details here:
https://github.com/coreos/etcd/blob/master/Documentation/admin_guide.md#fault-tolerance-table

The default cf-release templates normally have two instances in one zone,
and a single instance in the other zone.
