App Store API - submit for Beta review (Testflight)

Description of the feature request

Currently using Fastlane Spaceship which uses Transporter with user credentials. Ever since Apple introduced 2-factor auth it is very difficult to handle. The App Store API is now open to the public and is intended to be used with API keys that don’t expire.

Use case / for what or how I would use it

Put in the end of my Beta workflow to publish build to testers.

Thank you for the feature request, if the API came out we will definitely rework some of out steps. :upside_down_face:
