We want to switch from using a single limit to a dual soft/hard limit. As a first step we switch the limit field of `query_class_config` to use the recently introduced type for this. As this field has a single user at the moment -- reverse queries (and not a lot of propagation) -- we update it in this same patch to use the soft/hard limit: warn on reaching the soft limit and abort on the hard limit (the previous behaviour).
