Updated Google Play Developer API to version v3. Earlier API versions will be deprecated on December 1, 2019 (https://android-developers.googleblog.com/2019/03/changes-to-google-play-developer-api.html).

Removed APK file path (apk_path) input after a deprecation period, please use 'App file path` (app_path) instead.

Removed Untrack blocking versions? (untrack_blocking_versions) input. Other than the current target track releases are not changed, as it is not needed with the current API.
