SupportsStreamingUpdateAsAppend

trait SupportsStreamingUpdateAsAppend extends WriteBuilder

An internal WriteBuilder mixin to support UPDATE streaming output mode. Now there's no good way to pass the keys to upsert or replace (delete -> append), we do the same with append writes and let end users to deal with.

This approach may be still valid for streaming writers which can't do the upsert or replace. We can promote the API to the official API along with the new API for upsert/replace.
