This issue serves as a place to track the remaining 👊-items for merging tq-master into master.

Original proposal: #1651.

To-do

• tq: prioritize transferring retries before new items #1758: Priority Retries
• Manifest config attempt 2 #1767: De-couple config package, use interface instead.
• Change Adapter Begin() signature to accept an AdapterConfig interface #1774 Change Begin function to use a *tq.Manifest
• tq: simplify usage of tq.Transfer #1772: Introduce a tq.Object to replace use of *tq.Transfer, tq.Transferable and *api.ObjectResource.
• Split adapter implementations into sub-package: tq/transferadapter (name pending).
