Subject: [PATCH] ExecutorConfigType should be cacheable

Apparently the cache_ok attribute must be applied to all subclasses too.  So we must apply it here.  This allows sqlalchemy to use the caching behavior introduced with version 1.4.  See https://docs.sqlalchemy.org/en/14/core/type_api.html#sqlalchemy.types.ExternalType.cache_ok for more info.
