What version of qemu-img are you using? I found [1] this when poking around on my qemu server when checking for rbd support. This version (note it's proxmox) has rbd listed as a supported format.
[1]
# qemu-img -V; qemu-img --help|grep rbd
qemu-img version 2.11.2pve-qemu-kvm_2.11.2-1

Is it possible to use qemu-img with rbd support on Debian Stretch?
I am on Luminous and try to connect my image-buildserver to load images into a ceph pool.root@buildserver:~# qemu-img convert -p -O raw /target/test-vm.qcow2 rbd:rbd_vms_ssd_01/test_vm
qemu-img: Unknown protocol 'rbd'

The newer versions of Ceph (from mimic onwards) requires compiler
toolchains supporting c++17 which we unfortunately do not have for
stretch/jessie yet.
