Review Comment:
So the original reason for the return value is so that you can easily
replace it with `until`. Regarding extending the
`retryOnExceptionWithTimeout()`, the reason why `retryUntil` is handcoded is
because its keeping the same unwrapping `RuntimeException` that the original
`until` did (see
https://github.com/apache/kafka/blob/4c9eeef5b2dff9a4f0977fbc5ac7eaaf930d0d0e/streams/src/test/java/org/apache/kafka/streams/integration/StoreQueryIntegrationTest.java#L559-L563).
I don't know the original reason why it was done this way but the intention
was to minimize the amount of changes as to not increase the flakiness (but
this is a hunch). Are you happy with just removing the `return` value for now
or do you also want to extend ``retryOnExceptionWithTimeout()`?
