[WIP][DO NOT MERGE] Proposal: Auto-scaling

Auto-scaling is a feature that allows users to increase capacity as needed by controlling the number of replicas deployed within the system based on request statistics. Auto-scaling is bidirectional, it will scale up to a specified limit as requests increase and scale down to minimal capacity as the requests decrease.

I don't know that this is a valid assumption.  Rephrase - "Initially, most thresholds will be set by application administrators.  It should be possible for an autoscaler to be written later that sets thresholds automatically based on past behavior (CPU used vs incoming requests)."
