Analysis Workspace export reports to AWS S3 or other storage service

[#1]

It would be useful to be able to export reports from the Analysis workspace into AWS S3 or some other storage service, since the only option, as of today, is to export via email.

Although you can use the data warehouse tool to export data into an S3 bucket, the analysis workspace offers some features that are unavailable in the data warehouse, like the use of calculated metrics.
