    xenapi: implement xenserver image to volume
    
    Amend image_utils, so that it could handle xenserver type images (vhd
    chains inside a tgz archive). This requires the vhd-util binary, if the
    image contains a vhd chain (e.g.: snapshot)
    
    DocImpact
    - Copy a XenServer type OpenStack image (tgz -ed vhd chain) is now
      supported.
    - To use the above functionality, the cinder box must have access to the
      vhd-util binary. In ubuntu, this is done by apt-get installing
      blktap-utils.
