* Added `encode` attribute to [Live Entity](https://docs.uiza.io/api-reference/live-entities) .
* Introduced [Video Profile](https://docs.uiza.io/api-reference/video-profiles) & [Video Preset](https://docs.uiza.io/api-reference/video-presets) to support live with `encode` option.
* Added new attribute `preset` in  [Live Entity](https://docs.uiza.io/api-reference/live-entities) .

### Changes

* Live Session attribute `entity_id` changed to `live_entity_id`  to differentiate with `video_entity_id`.
* Following [Google API Design guideline](https://cloud.google.com/apis/design/standard_methods#delete), all `DELETE` APIs should return empty body.
* Remove `Reset ingest key` API in version 2020-01-10. We no longer support resetting ingest key, because conflicts with the end of signal occurs when an user resets the ingest key while streaming. We are working on this problem.
* Remove emit event log form. All event logs related to entity should be executed in Live Entity server.
* Update submodule by removing `googleapis`. This update shortens the times of build time from 10 minutes to about 2 minutes.
