Do it now, in case this function is re-used. The code is easier to

block/rbd: Add support for ceph namespaces
Starting from ceph Nautilus, RBD has support for namespaces, allowing
for finer grain ACLs on images inside a pool, and tenant isolation.
In the rbd cli tool documentation, the new image-spec and snap-spec are :
- [pool-name/[namespace-name/]]image-name
- [pool-name/[namespace-name/]]image-name@snap-name
When using an non namespace's enabled qemu, it complains about not
finding the image called namespace-name/image-name, thus we only need to
parse the image once again to find if there is a '/' in its name, and if
there is, use what is before it as the name of the namespace to later
pass it to rados_ioctx_set_namespace.
rados_ioctx_set_namespace if called with en empty string or a null
pointer as the namespace parameters pretty much does nothing, as it then
defaults to the default namespace.
The namespace is extracted inside qemu_rbd_parse_filename, stored in the
qdict, and used in qemu_rbd_connect to make it work with both qemu-img,
and qemu itself.

qemu-storage-daemon: Add --chardev option
This adds a --chardev option to the storage daemon that works the same
as the -chardev option of the system emulator.
The syntax of the --chardev option is still considered unstable. We want
to QAPIfy it and will potentially make changes to its syntax while
converting it. However, we haven't decided yet on a design for the
QAPIfication, so QemuOpts will have to do for now.

qemu-storage-daemon: Add main loop
Instead of exiting after processing all command line options, start a
main loop and keep processing events until exit is requested with a
signal (e.g. SIGINT).
Now qemu-storage-daemon can be used as an alternative for qemu-nbd that
provides a few features that were previously only available from QMP,
such as access to options only available with -blockdev and the socket
types 'vsock' and 'fd'.

qemu-storage-daemon: Add --export option

--export nbd,device=disk,name=test-export,writable=on

Add a --nbd-server option to qemu-storage-daemon to start the built-in

SocketAddressLegacy: New interfaces shouldn't use legacy types, and the
additional nesting would be nasty on the command line.

qapi: Flatten object-add
Mapping object-add to the command line as is doesn't result in nice

'props' is still accepted after this patch, but marked as deprecated.

This adds a --blockdev option to the storage daemon that works the same

In contrast to the system emulator, qemu-storage-daemon options will be
processed in the order they are given. The user needs to take care to
refer to other objects only after defining them.

options --version, --help and --trace.
Even though this doesn't add any options yet that create things (like
--object or --blockdev), already document that we're planning to process
them in the order they are given on the command line rather than trying
(and failing, like vl.c) to resolve dependencies between options
automatically.
