Google Sheets proxy #6
Description
A Google Apps organization may have a security/privacy policy that disallows third party applications from having access to a domain user's Google Drive folder via oauth2. Oauth2 integration is how Grow currently integrates with Google Sheets.
While this policy is not common, it does exist. We should leverage Jetway as a proxy for Google Apps organizations with this policy. Users should be able to share Google Sheets with the Jetway service/role account. When Grow downloads the sheet, instead of downloading it from Google Sheets, it should be downloaded from Jetway, which would act as a proxy.
If necessary, Jetway can check to see if the requesting user is in the sheet's ACL. Otherwise, the sheet is public to all sites using Jetway as a proxy.
