control: Remove ZoneHandlers from JSON zone object

The ZoneHandlers will not be needed once the properties configured for a
JSON based zone object are parsed and set on the object. This was
something needed for YAML based zone objects to correctly configure
interfaces/properties on the zone objects since they came from a YAML
configuration file.
