docstring: Returns the maximum size of the Dropbox files to cache in moodle.
  
  Note that {@link repository_dropbox::sync_reference()} will try to cache images even
  when they are bigger in order to generate thumbnails. However there is
  a small timeout for downloading images for synchronisation and it will
  probably fail if the image is too big.
