ExponentialBackoffStrategy

A strategy to calculate an exponential backoff.

The formula is as follows. The randomValue value is [1.0, 1.0 + randomFactor].

minBackoff * (multiplier ^ (trialTimes - 1)) * randomValue

However, nextDelay returns maxBackoff * randomFactor if the calculated backoff exceeds maxBackoff.
