Review Comment:
I think it is better for RestCatalog to maintain a separate implementation
to make a head request to
[/v1/{prefix}/namespaces/{namespace}/tables/{table}](https://github.com/apache/iceberg/blob/main/open-api/rest-catalog-open-api.yaml#L814),
ref: https://github.com/apache/iceberg-python/pull/512#discussion_r1519661896,
https://github.com/apache/iceberg-python/issues/507#issue-2177108431
The try-catch implementation is for other non-rest catalogs and thus it is
put in the `MetastoreCatalog` instead of the `Catalog` interface.
A little bit more context regarding the `MetastoreCatalog`: while working on
https://github.com/apache/iceberg-python/pull/498, we found that many helper
functions as well as some implementations are for non-rest catalogs only. So we
decide to move those to another layer, `MetastoreCatalog` to make the
inheritance look better:
