Some cache_bench enhancements ( #11661 ) ...
Summary:
... used in validating some HyperClockCache development in progress.
* Revamp the "populate cache" step to avoid redundant insertions (very rare in practice) and more consistently approach the desired resident_ratio while maintaining appropriate skew (still not perfect).
* Track and print hit ratio on lookups, to ensure a fair comparison is happening between implementations etc.
* Add an option to disable tracking and printing histograms (lots of output)
* Add an option to specify a random seed (for more reproducibility)
* Remove confusing/redundant "-skewed" option
Uses BitwiseAnd from https://github.com/facebook/rocksdb/issues/11660 (tested there)
