2017-11-18Adding exponential backoff utilitiesmdooley
This cl adds two classes, one to calculate a base multiplier for an exponential backoff series and the other to return sequential values in an exponential backoff series. This cl has a number of advantages over the previous one, such as: - separating the base multiplier calculation from the exponential backoff class so that a standard exponential backoff class like com.google.common.labs.concurrent.RetryStrategy.ExponentialBackoff could be used instead if it becomes open source - allows the backoff sequence to be scaled by specify an initial backoff delay - uses milliseconds instead of arbitrary time units which allows the tolerance to be set automatically when calculating the base multiplier WANT_LGTM=zachh Bug: 66966157 Test: unit tests PiperOrigin-RevId: 176130268 Change-Id: I75135d4df16f642ea9dd3ef9ff9498981beae2c6
