Hi,

Hum, but you want to add this definition in all our modules, or directly in
openstacklib?

In case of openstacklib, in which manner do you define the <component>_config
resource? (eg, generic def, but specialized resource).

I'm not sure to see the difference with the Yanis solution here¹, and not sure
to see the link between the define resource and the type/provider resource.
