UsingStatement Formatting

[belav]

This may be cleaned up by InvocationExpression. Do that formatting first.

            using (var http = new HttpClient())
            using (var stream = Assembly.GetExecutingAssembly().GetManifestResourceStream(
                "GraphQLApiGenerator.MetadataQuery.gql"))
            using (var queryReader = new StreamReader(stream))
            using (var content = new ByteArrayContent(
                Encoding.UTF8.GetBytes(
                    JsonConvert.SerializeObject(
                        new { query = await queryReader.ReadToEndAsync() }))))
            {

Currently looks like this, could probably be improved

        using (var http = new HttpClient())
        using (var stream = Assembly.GetExecutingAssembly()
            .GetManifestResourceStream("GraphQLApiGenerator.MetadataQuery.gql"))
        using (var queryReader = new StreamReader(stream))
        using (var content = new ByteArrayContent(
            Encoding.UTF8.GetBytes(
                JsonConvert.SerializeObject(
                    new { query = await queryReader.ReadToEndAsync() }
                )
            )
        ))
        {
            return;
        }

This should be looked at after #7

The only improvement I see will come with #451
