* Refactoring of standard metrics extractors and data structures * Removed optional value in Metric, simplified a lot * Configuration of EWMA by using half-life duration * Renamed DataStream to EWMA * Incorporate review feedback * Use binarySearch for selecting weighted routees * More metrics selectors for the router * Removed network metrics, since not supported on linux * Configuration of router * Rename to AdaptiveLoadBalancingRouter * Remove total cores metrics, since it's the same as jmx getAvailableProcessors, tested on intel 24 core server and amd 48 core server, and MBP * API cleanup * Java API additions * Documentation of metrics and AdaptiveLoadBalancingRouter * New cluster sample to illustrate metrics in the documentation, and play around with (factorial)
