Set region to the availability zone name on VM infrastructure
During production#3094 (closed) it was a bit difficult to spot that we were having problems on the front-end (HAProxy nodes) on us-east1-b.
to make our vms more consistent with kubernetes infrastructure, @andrewn and I discussed setting region
to the AZ name, for consistency.
Currently, it is hardcoded to us-east
in our chef role.
We can get the zone from chef with node.to_h.dig('gce', 'instance', 'zone')
