I'm currently adding a new module on ansible-collections-openstack, however, I'm having a hard time finding the appropriate function for my module.

Within ansible-collections-openstack, we have a compute_services_info module that list services using the conn.compute.services() function that, to my knowledge, come from the openstacksdk.compute.v2.service.py module.

Our ansible module replicate what you get with:
openstack --os-cloud compute service list command.
or

openstack --os-cloud volume service list command.
(If I'm not wrong, it seems, openstack client is leveraging osc-lib for that and not the SDK).

My problem is, I want to add another similar module on our collection, (volume_services_info) that would do the same but for volumes services: 

Unfortunately, either I'm not looking at the right place, or any volume endpoint (v2/v3) within the openstack sdk is implementing the appropriate service module.

Did I miss something or is that class simply missing?

Thanks everyone!
