[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.

This reads weird.  Just say "while the proxy provides internal inter pod connections, there will be L3 and L7 proxies and load balancers that manage traffic to backends.  OpenShift, for instance, adds a "route" resource for defining external to internal traffic flow.  The "routers" are HAProxy or Apache load balancers that aggregate many different services and pods and can serve as a data source for the number of backends."
