REST catalog resets snapshot-logs when replacing tables as I filed https://github.com/apache/iceberg/issues/11777.
The cause is `RESTSessionCatalog.Builder#replaceTransaction` calls `TableMetadata#buildReplacement` which adds a `RemoveSnapshotRef` request, and then REST `CatalogHandlers.commit` clears snapshot-logs during the request processing. I propose adding a new flag (e.g. boolean purge) to `RemoveSnapshotRef` so the catalog can skip clearing snapshot-logs. https://github.com/apache/iceberg/pull/11779 is the proposed change. BR, Yuya
