   import a cloud image to your local cloud.
   Image is downloaded from Ubuntu cloud-images site and published
   to the cloud configured.

   options:
      --save-downloaded     save the downloaded image in '.'
      -q | --quiet          be quiet, only output the AMI id registered
           --disk           use the disk image (default is partition)
           --stream         stream: 'released' or 'daily' (default: released)

   the following options pass through to cloud-publish-tarball
   or cloud-publish-image:

      -l|--add-launch ID      : ID can be "all", or "none", or numerical ID
         --allow-existing     : if a image is already registered
                                simply report as if work was done
      -o|--output <file>      : write registered id and manifest to file

         --save-downloaded    : if the image is a url, save it to '.'
         --image-to-raw       : convert disk format to raw before publishing

      -l | --use-loader       : use the loader kernel rather than linux kernel
      -k | --kernel  k        : use previously registered kernel with id 'k'
                                specify 'none' for no kernel
      -K | --kernel-file f    : bundle, upload, use file 'f' as kernel
      -r | --ramdisk r        : use previously registered ramdisk with id 'r'
                                specify 'none' for no ramdisk
      -R | --ramdisk-file f   : bundle, upload, use file 'f' as ramdisk
           --resize  s        : resize the partition image before uploading
                                's' must be valid input to cloud-resize-image
      -B | --block-device-mapping m : specify block device mapping in bundle
