Possibility to set Initial delay

Is there a way to set up initial delay before first attempt? If no would be nice to have such possibility.

My current retry config looks like this: ``` RetryConfig config = RetryConfig.custom() .maxAttempts(exponentialRetryConfiguration.getMaxAmountOfAttempts()) .intervalFunction(intervalFn) .build();

Maybe custom, provided implementation of intervalFunction (with specific first interval as a delay) would help.

You are right. The waitDuration property is ignored, if a custom interval function is used. The config property ``waitDurationjust a shortcut for a constant interval function like(numOfAttempts) -> waitDuration.toMillis()`

The initial wait duration is calculated at runtime as follows:

long interval = intervalFunction.apply(numOfAttempts.get());

In your case the initial delay before the first retry attempt is config.getInitialExponentialDelay().
