[Improvement] IcebergRESTServer should not use Gravitino iceberg catalog with REST backend

[FANNG1]

What would you like to be improved?

This may cause deadlock, if IcebergRESTServer using the Gravitino Iceberg catalog with the same Iceberg REST address.

GravitinoBasedIcebergCatalogWrapperProvider.java#getIcebergTableOps()

   Catalog catalog = client.loadMetalake(gravitinoMetalake).loadCatalog(catalogName);
    Preconditions.checkArgument(
        "lakehouse-iceberg".equals(catalog.provider()),
        String.format("%s.%s is not iceberg catalog", gravitinoMetalake, catalogName));
   // should check catalog backend in catalog.properties()

How should we improve?
