Create new import data for S3, Google Cloud, Google Drive, Azure, Box

[tyson-swetnam]

Similar to the other import data from CyVerse DataCommons, we want to import files from S3 Buckets, Google Drive, and Box accounts. These will likely use the same https:// protocols as the other imports, but they need to allow user to pop open a browser pane or a web view to authenticate their user name and passwords from those services.

This may require separate Import Tabs for S3, Google, etc.
