Description

currently it only have redeliverInterval,but with redeliverIntervalFactor ,we could keep the behavior the same as currently by set it default as 1,but we could reduce the overhead when there is a suddenly spike. so if we have the RedeliverInterval = 1s and a redeliverIntervalFactor = 2,then we have 1s,2s,4s...etc

Contributor guide

Research direction
Investigate the existing redelivery mechanism in Akka's AtLeastOnce delivery and implement exponential backoff by adding a redeliverIntervalFactor configuration parameter. Study the current implementation and test files to understand the pattern.
