exception cause chain inspection useless for default Retry.retryOn / Fallback.applyOn / CircuitBreaker.failOn

[Ladicek]

When Retry.retryOn / Fallback.applyOn / CircuitBreaker.failOn is left to the default value, which is either Exception.class or Throwable.class, it matches all exceptions and the exception cause chain is never inspected. This is exactly as documented, but also pretty much useless. Need to figure out a better definition of cause chain inspection.
