    Allow to change boot order and close tray for Node

    - Added Node.set_boot() - allows to set new boot order on node
      example:
          node.set_boot(['cdrom', 'hd'])

    - Added Node.close_tray() - allows to close cdrom tray.
      (Closes trays of all cdrom devices on selected node)

    - Changed DevopsDriver.volume_upload - these changes allow to upload
      a new image to existing volume. if there is no enough space
      virStorageVol.resize will be called to increase size of the volume
      to be equal to size of the new image file.
