[PATCH v3 24/30] qemu-nbd: Use user_creatable_process_cmdline() for --object
This switches qemu-nbd from a QemuOpts-based parser for --object to
user_creatable_process_cmdline() which uses a keyval parser and enforces
the QAPI schema.
Apart from being a cleanup, this makes non-scalar properties accessible.
