This creates a response_stream plugin in the Kibana /examples section. The plugin demonstrates API endpoints that can stream data chunks with a single request with gzip/compression support. gzip-streams get decompressed natively by browsers. The plugin demonstrates two use cases to get started: Streaming a raw string as well as a more complex example that streams Redux-like actions to the client which update React state via useReducer().
