Describe the bug
The add-disk / disk command does not match the OpenAPI spec.

The DiskConfig requires the path to be present which does not allow to add a vhost devices using a vhost_socket only.

The path and vhost_socket should be mutually exclusive.

To Reproduce
Steps to reproduce the behavior:

• Generate a Client based on the OpenAPI spec
• DiskConfig with path required enforces that path is being set
• Validation hits Failed to validate config: Disk path and vhost socket both provided
