Bikeshedding ahead:  Maybe this should be called qemu_rados_connect()?
I don't know anything about this, but there seems to be a distinction
between rados_* functions and rbd_* functions -- the former work on the
pool, the latter on the single block device.

Since this function only connects to the pool and not to a single device
within, I think it should be called qemu_rados_connect() instead of
qemu_rbd_connect().

(Also because qemu_rbd_connect() seems so similar to qemu_rbd_open().)

Up to you:
