- org.apache.cloudstack.api.response.TemplateZoneResponse (at
org.apache.cloudstack.api.response.TemplateResponse, there is this
comment "To avoid breaking backwards compatibility, we still treat a
template at different zones as different templates, so not embedding
template_zone information in this TemplateZoneResponse set. `private
Set<TemplateZoneResponse> zones;`" but right now it is not used)
