KuCoin API deprecated POST /api/v1/margin/toggle-auto-lend without giving a shutdown date yet.

KuCoin deprecated the POST /api/v1/margin/toggle-auto-lend endpoint without a shutdown date, announcing plans to abandon the interface. Calls sent to this endpoint fail. Any integration relying on this auto-lend feature is affected.

## What to use instead
