Since Nautilus ceph supports separate image namespaces within a pool for tenant isolation and QEMU adds it as a rbd blockdev options from 5.0.0. The source name with format "<pool>/<namespace>/<image>" could be used to access a rbd image with namespace.
Add unit tests for this attribute.

So, prior to patch 2/3 in this series ...
+ <disk type='network' device='disk'> + <driver name='qemu' type='raw'/> + <source protocol='rbd' name='pool/ns/image'>
what would this refer to when used with qemu? this woudl become: "pool": "pool", "image": "ns/image"

and this: "pool": "pool", "image": "/image" Are those valid names in RBD? if yes, this will most probably cause a regression.

This removed the extra '/', but it depends on the semantics of the previously existing code whether that's okay or not.
