> We need a way to run a command for all data in the cache (while under a lock) but also return a value for the data processed.
> There are a few different APIs we could do for this having a {{Cache<K, V>}}
> blocking variant
> {code}
> <R> Map<K, R> evalAll(BiFunction<Cache<K, V>, ? super CacheEntry<K, V>, R> biFunction)
> {code}
> back pressure aware variant  - this would have to be a hot observer on subscribe
> {code}
> <R> Publisher<R> evalAll(BiFunction<Cache<K, V>, ? super CacheEntry<K, V> R> biFunction)
> {code}
