* MetricsSelector, calculate capacity, weights and allocate weighted routee refs * ClusterLoadBalancingRouterSpec * Optional heap max * Constants for the metric fields * Refactoring of Metric and decay * Rewrite of DataStreamSpec * Correction of EWMA and removal of BigInt, BigDecimal * Separation of MetricsCollector into trait and two classes, SigarMetricsCollector and JmxMetricsCollector * This will reduce cost when sigar is not installed, such as avoiding throwing and catching exc for every call * Improved error handling for loading sigar * Made MetricsCollector implementation configurable * Tested with sigar
