Renter to track repair churn
The allowance documentation now says that the user should disregard repair bandwidth when considering upload bandwidth and download bandwidth, because Sia will automatically consider repair bandwidth on its own.
Except, this is a complete lie
siad doesn't currently track repair churn nor estimate repair bandwidth, but it should because it should be reasonably well positioned to do so, and then it should account for that churn in storage, upload, and download costs.
