Jackson deserializes integers sometimes as int and sometimes as long,
depending on how big they are. This leads to ClassCastException
when comparing deserialized values as part of groupBy merging on the
broker.

This is useful for putting them behind load balancers or proxies, as it lets
the load balancer know which server is currently active through an http health
check.
Also makes the method naming a little more consistent between coordinator and
overlord code.
