share_folder

[share_folder](https://www.dropbox.com/developers/documentation/http/documentation#sharing-share_folder) scope: `sharing.write` Share a folder with collaborators. Most sharing will be completed synchronously. Large folders will be completed asynchronously. To make testing the async case repeatable, set `ShareFolderArg.force_async`. If a `ShareFolderLaunch.async_job_id` is returned, you'll need to call `check_share_job_status` until the action completes to get the metadata for the folder.
