Eric Zhao 044cdbb1bf Add occupy mechanism for future buckets of sliding window to support "prioritized requests final pass" (#568) ... * Rename: MetricsLeapArray -> BucketLeapArray * Add implementation for `FutureBucketLeapArray`, a kind of `BucketLeapArray` that only reserves for future buckets, which is used for calculating occupied future tokens. * Add OccupiableBucketLeapArray that combines common BucketLeapArray with FutureBucketLeapArray. The rollingNumberInSecond in StatisticNode now uses OccupiableBucketLeapArray by default. * Add OccupySupport interface. Node now implements OccupySupport interface. * Add occupy-related methods in Metric and ArrayMetric. * Handle prioritized requests in default traffic shaping controller. * Update default occupyTimeout to 500ms Signed-off-by: Eric Zhao <sczyh16@gmail.com>		2019-03-14 10:04:56 +08:00
