Task - Create deal monitoring/reconciliation worker

[en0ma]

Abstract all deal-monitoring/reconciliation code into this worker.

The basic idea is that this worker will continuously monitor the content_deals table for existing deals and check if they need repairs (slashed), need renewals (deals about to expire), or failed data transfer.

When a content_deal is about to expire(needs renewal), is slashed, or failed, the worker will create a replacement content_deal (which the deal-making worker will pick up) and mark the bad deal with its replacement_id.

The UI will show the deal is being replaced.
