Should help with MVP:

An instance of this should be more or less OK to try uploading user's data from an UI.

## TODO
   - [x] get user name from user service
   - [x] get user email from user service

Other than that, should be more or less ready to stand up in devel now.

I thought the event stuff would be useful, but it's turning out less useful than I had originally imagined.
I wouldn't mind removing it, but will leave it for now.
