Previous title: Add api_streaming extension and update api-example-stream to use it * Merge with latest main * Add parameter capturing encoder_repetition_penalty * Change some defaults, minor fixes * Add --api, --public-api flags * remove unneeded/broken comment from blocking API startup. The comment is already correctly emitted in try_start_cloudflared by calling the lambda we pass in. * Update on_start message for blocking_api, it should say 'non-streaming' and not 'streaming' * Update the API examples * Change a comment * Update README * Remove the gradio API * Remove unused import * Minor change * Remove unused import --------- Co-authored-by: oobabooga <112222186+oobabooga@users.noreply.github.com>
