[Feature] info.subgraph_sizes in sharded namespace view

まず、シャーディングされた名前空間ビューがどのように定義され、info.subgraph_sizes がどのように設定されるかを、issue の SQL クエリを想定される形として使用して追跡します。利用可能なシャーディング済みビューの列とサイズデータを比較し、要求されたサブグラフサイズフィールドがシャーディングされた名前空間ビューを通じてクエリ可能であることを確認します。

Description

Firstly thank you for the new sharded namespace, we are implementing new grafana dashboards using the views. We have a general health dashboard that we have adapted to work with the sharded namespace views (added to end of this post).

The query works apart from the subgraph size field. I believe this is in the info schema in each subgraph shard.

Would it be possible to bring this data into the new sharded namespace views to complete this overview of subgraph health?
