A resource which enables easily disabling certain resources via the

resource_registry. It does nothing, but can effectively stub out

any other resource because it will accept any properties and return

any attribute (as None). Note this resource always does nothing

on update (e.g it is not replaced even if a change to the stubbed

resource properties would cause replacement).
