Subject: cli: Add --disk driver.queue_size support
From: Lin Ma lma@suse.de Sun Jan 5 17:49:34 2025 +0800

Git: 36d00e0e79f3d845522201c4a353d5a529af82a7

Eg:
virt-install \
......
--disk /tmp/disk0.qcow2,size=10,driver.type=qcow2,\
driver.queues=4,driver.queue_size=256 \
......

It results in the following domain XML snippet:
    <disk type='file' device='disk'>
      <driver name='qemu' type='qcow2' queues='4' queue_size='256'/>
      <source file='/tmp/disk0.qcow2' index='2'/>
      <backingStore/>
      <target dev='vda' bus='virtio'/>
      <address type='pci' domain='0x0000' bus='0x05' slot='0x00' function='0x0'/>
    </disk>
