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.

@return int
