[GSS](7.4.z) Resource adapters - duplicate resource between attribute and children definitions

n /subsystem=resource-adapters we have an attribute named config-properties (type STRING) and a child resource with the same name. Since read-resource doesn't distinguish between attributes and children it looks like they end up overwriting each other. The attribute seems to be completely ignored so I don't think there's a bug but it's a bit confusing when dealing with DRM operations.

Also the child resource has a single STRING attribute so it feels like it would be simpler to have an OBJECT of STRING.
