This is a tool to help developers quantify changes to the ring builder. It takes a scenario (JSON file) describing the builder's basic parameters (part_power, replicas, etc.) and a number of "rounds", where each round is a set of operations to perform on the builder. For each round, the operations are applied, and then the builder is rebalanced until it reaches a steady state. The idea is that a developer observes the ring builder behaving suboptimally, writes a scenario to reproduce the behavior, modifies the ring builder to fix it, and references the scenario with the commit so that others can see that things have improved. I decided to write this after writing my fourth or fifth hacky one-off script to reproduce some bad behavior in the ring builder. Change-Id: I114242748368f142304aab90a6d99c1337bced4c
