Return a Python dictionary of metadata configuration values. The ``metadata_value`` argument will be the value passed to the ``-m`` or ``--metadata`` argument to ``datasette serve``.
Only one plugin can implement this at a time. The first registered plugin will get to provide the metadata dictionary, while all other plugins will be ignored.
