Title: rbd: use cout instead of cerr for progress

The qemu test suite expects stdout to be silent on success and will
complain otherwise. Although it could be argued that a reliable exit
code is the only proof of success / failure, reserving stderr to error
message sounds like a sensible thing to do.
