New Call: getHandlingTime for SKU's by warehouse

A new call has been released, getHandlingTime, that enables users to retrieve their product and kit SKU's handling time by warehouse per Amazon channel account in SkuVault. You must first use getTokens to acquire user and tenant tokens (which are unique). Then you can use those tokens to retrieve a product and kit's handling time by SKU and by warehouse ID. Use getWarehouses if you are unsure of the ID('s) for your warehouse(s).
