 * Build an IntrospectionQuery from a GraphQLSchema
 *
 * IntrospectionQuery is useful for utilities that care about type and field
 * relationships, but do not need to traverse through those relationships.
 *
 * This is the inverse of buildClientSchema. The primary use case is outside
 * of the server context, for instance when doing schema comparisons.
