qemu-nbd: allow specifying image as a set of options args
Currently qemu-nbd allows an image filename to be passed on the command line, but unless using the JSON format, it does not have a way to set any options except the format eg qemu-nbd https://127.0.0.1/images/centos7.iso qemu-nbd /home/berrange/demo.qcow2 This adds a --image-opts arg that indicates that the positional filename should be interpreted as a full option string, not just a filename. qemu-nbd --image-opts driver=https,url=https://127.0.0.1/images,sslverify=off qemu-nbd --image-opts driver=file,filename=/home/berrange/demo.qcow2 This flag is mutually exclusive with the '-f' flag.
