RetryPolicy exception aware timeout #37588
Description
We would like to have a way to use different timeout values between tries depending the thrown exception.
For example: A race condition resulting in DataIntegrityViolationException could be retried after 100ms; while a ServiceUnavailableException might need a little bit more time to recover successfully.
Workaround:
Using setRetryPolicy with different timeouts depending on the exception available inside onRetryableExecution right before the timeout is evaluated.

I can consider adding this if the group feels this is within the scope of the retry core.
This could take the form of a BackOff which selects a delegate based on the last thrown exception as configured using RetryPolicy.Builder (for instance .backOffFor(DataIntegrityViolationException.class, Duration.ofMillis(100)) with the current backoff as fallback). The matching would happen according to exception type inheritance similar to how includes/excludes currently work. In case a different structure would be preferred like a Function<Throwable,Duration> callback, I am open to do that too.
