Delay multiplier

The multiplier to apply to the delay between each retry attempt. The system will multiply the delay by this value after each retry attempt. For example, if the delay is set to 1000 milliseconds and the delay multiplier is set to 2, the system will wait 1000 milliseconds before the first retry, 2000 milliseconds before the second retry, 4000 milliseconds before the third retry, and so on.
