   @jiazhai Just as I've said, appending a ledger is more efficient so it's the default behavior of delete schema. However, when we want to delete the topic but not only delete the schema, we need to delete the ledger instead of creating a new ledger. So we need to add an option to *delete* the schema when delete a topic.
   
   The current `deleteSchema` parameter of `deleteTopic` was not exposed, i.e. the API is like `deleteTopic(deleteSchema = false)` and is always called as `deleteTopic(false)`.
   
   By the way, the behavior of this parameter is also simply appending a new ledger, so we need to change it to deleting the existed schema ledgers.
