ui: add a function to read configuration related to devel warning

We are about to introduce a class of configuration that will enable various
warnings targeted to developers. As we want both a wide and fine way to control
them, we introduce a special method to know if a warning of a given category
should be displayed or not.

First user will be introduced in the next changeset.
