Lab: reliability is not retry=3¶

One in-process origin and forty concurrent callers, through six client configurations: no retries, retry=3, retry under a one-second deadline, retry with a budget, retry with a per-origin circuit breaker, and two waves through the same client so the breaker has seen the failures. For each: how many requests the origin received, how many callers were served, how long the slowest waited, and how long after the origin healed the first caller got through.
