StreamSinkProvider Contract

StreamSinkProvider is the abstraction of providers that can create a streaming sink for a file format (e.g. parquet) or system (e.g. kafka).

StreamWriteSupport is a newer version of StreamSinkProvider (aka DataSource API V2) and new data sources should use the contract instead.
