Removed image_path parameter from cli config
  As per the new design, cli does not need to interact with db or image file system. To reflect this image_path parameter is removed from cli/config/hanlon_client.config file
  However, cli/hanlon image command tries to build image path based on this parameter assuming image file system path as local path. To reflect the change, two output parameters image path and image status are temporarily hardcoded to Not Available and unknown respectively.
  This requires a change in image get REST API to build and return these parameters from server
