Allow middleware to save Cloud Sync setting even if bucket listing failed
I'm using the free tier of Blackblaze B2 (10gb) to test out online backup solutions. I found my configuration was uploading too much during the day. Unfortunately, I can not change FreeNAS' Cloud Sync setting from every hour to one a day because the daily transaction cap is hit within Backblaze and FreeNAS interprets this as a failed connection.
Once should be able to add/edit clod sync tasks normally. We also should be able to edit a cloud sync task when the credentials fail (transmission cap, access denied, etc)
