Description
We want ARI to be able to do dynamic load smoothing. Based on past traffic patterns and expectations for future patterns, it can recommend renewal windows for certs that will relieve upcoming load spikes and/or fill in current/upcoming load valleys.
Context: The first draft of ARI implemented in #5674 is very unintelligent: it just returns a suggested renewal window approximately 2/3rds of the way through the validity period of the cert. While this implements the draft API, it does not satisfy any of the motivations behind the draft.
Goal: Design and implement a mechanism for ARI to be able to return dynamic renewal windows based on predicted load.

Research direction
Start by reviewing the first ARI draft in issue #5674 and the current ARI behavior described there. The work is complete when ARI can return renewal windows that respond to predicted traffic patterns rather than using a fixed point in the certificate validity period.
