Public bug reported:

Right now, there's only one set of options for rbd_user and
rbd_secret_uuid in nova.conf.  When it is set, it will be used

- for images when images_type=rbd is set: https://github.com/openstack/nova/blob/c15dff2e9978fe851c73e92ab7f9b46e27de81ba/nova/virt/libvirt/imagebackend.py#L79-L80
- for volumes, it will override whatever glance has provided: https://github.com/openstack/nova/blob/c15dff2e9978fe851c73e92ab7f9b46e27de81ba/nova/virt/libvirt/volume.py#L217-L229

Therefore, when you intend to use RBD for images and for volumes, you'd
have to use the same user for _both_.
