qga/qapi-schema.json: Add some headings

Add some section headings to the QGA json; this is purely so that we
have some H1 headings, as otherwise each command ends up being
visible in the interop/ manual's table of contents.  In an ideal
world there might be a proper 'Introduction' section the way there is
in qapi/qapi-schema.json.
