> Iceberg REST Catalog provides `/v1/\{prefix}/namespaces/\{namespace}/tables/\{table}/plan`, which pushes scan planning to the server side.
> [https://github.com/apache/iceberg/blob/apache-iceberg-1.10.1/open-api/rest-catalog-open-api.yaml#L605-L689]
> This effort could benefit users.
>  - Read performance can improve if the catalog effectively caches the response
>  - Clients can be thin; beneficial for new languages
>  - With credential vending, we can give more fine-grained credentials
> In this ticket, we will try to implement the simplest mode of the server-side scan planning.
