Title: Make servers default value an empty array

Make the default value an empty array, otherwise if nothing is set for $servers, when the zoo.cfg.erb gets provisioned you end up with

server.1=

Which results in zookeeper not starting up correctly.
It should only render out the server list in the template if we have actually supplied any servers
