[ovirt-users] The equivalence of the DiskAttachment ID and its relevant Disk ID should be intuitively documented.

Hi all, In these days, I was struggling to find the relationship among vm/disk/disk-attachment. I just found that the IDs of DiskAttachment and relevant Disk are the same, in the mapping phrase by [1]. This is a extremely helpful for connecting the disk and the disk-attachment, especially when updating a disk by its relevant disk-attachment instance. Nevertheless it's missing in the API document [2]. Adding a intuitive hint would be highly appreciated. Thanks. [1]: https://github.com/oVirt/ovirt-engine/blob/68753f46f09419ddcdbb6324535012...
