ARTEMIS-833 maxHops defaults to 0 when creating artemis cluster configuration through cli

https://issues.apache.org/jira/browse/ARTEMIS-833

The generated broker.xml configuration file has the <max-hops/> element
set to 0. This is very confusing since it effectively disables message
load balancing and stop cluster from forwarding messages to other nodes
in hte cluster. This should be set to at least 1.
