serve and publish commands now take a --metadata option

Browse source 
If provided, the --metadata option is the path to a JSON file containing
metadata that should be displayed alongside the dataset.

    datasette /tmp/fivethirtyeight.db --metadata /tmp/metadata.json

Currently that metadata format looks like this:

    {
        "title": "Five Thirty Eight",
        "license": "CC Attribution 4.0 License",
        "license_url": "http://creativecommons.org/licenses/by/4.0/",
        "source": "fivethirtyeight/data on GitHub",
        "source_url": "https://github.com/fivethirtyeight/data"
    }

If provided, this will be used by the index template and to populate the
common footer.

The publish command also accepts this argument, and will package any provided
metadata up and include it with the resulting Docker container.

    datasette publish --metadata /tmp/metadata.json /tmp/fivethirtyeight.db
