Document RoleARN configuration parameter
What does this MR do?
In !5246 (merged)
we added a RoleARN configuration parameter that supersedes
UploadRoleARN. While UploadRoleARN only handles uploads,
RoleARN also handles multipart downloads--which significantly
improves transfer speeds for large downloads.

To document !5246 (merged).
