Ryan Weaver 037a782b91 Making tags under _defaults always apply and removing inherit_tags entirely
Now that inherit_tags has been removed, 3.3 has the same functionality as 3.2: tags
are *never* cascaded from parent to child (but you tags do inherit from defaults
to a service and instanceof to a service).
