OneDrive sync support (beta)

I'm exploring the beta support for OneDrive sync, and found several shortcomings that I'd like to see addressed in updates to the 6.9.0 firmware:

1. Shared folders that are added to my OneDrive aren't sync, while on Windows and Mac clients they are sync'd. The NAS should sync them as well. This has been committed as a 6.9.1 feature, which is great.

2. There is no multi-user support, though it really needs to be added. User A should be able to sync their OneDrive to their own share, while user B should be able to log in and establish a separate OneDrive authentication and sync relationship in their own share.

3. There is no way to ascertain sync state / progress.  Somewhere there needs to be a progress indicator or "files remaining to be sync'd." Otherwise, users have no idea whether their ReadyNAS is in a clean or dirty sync state, thus no confidence of a full copy of their data.

4. You should document that a 0 means "no bandwidth restriction" rather than "0 KBps allowed". 

Thanks,
Jeff
