CalculateDelay returns delay distributed from initialDelay to default maxDelay (32s) Example: Retry 0: 5s Retry 1: 6s Retry 2: 7.8s Retry 3: 9.8s Retry 4: 13s Retry 5: 21s Retry 6: 32s Retry 7: 32s.

CalculateDelayWithMax returns delay distributed from initialDelay to maxDelay based on retryCount number.

Each delta delay is twice bigger.

Each delay has random additional milliseconds.

ExponentialCalculationsCount counts of exponential calculations before return max delay to prevent overflow with big numbers.
