api: support streaming from Google Drive remotes

[jorgeorpinel]

Extracted from treeverse/dvc.org#908 (comment)

GDrive is the only remote type that doesn't support file streaming. Should we work on adding it?

• and update docs (e.g. api ref)

p.s. maybe could be included in #2865 and closed here.

@jorgeorpinel yes, let's add a check box to that list and keep/remove this ticket - I don't have a strong preference
