sentinel之三種熔斷降級狀況的驗證

熔斷降級是指當資源處於不穩定的狀況下，在接下來的時間窗口以內，對該資源的調用都自動熔斷（默認行爲是拋出DegradeException）。
一般用三種方式來衡量資源是否處於穩定的狀態：

平均響應時間 (DEGRADE_GRADE_RT)：當資源的平均響應時間超過閾值（DegradeRule 中的 count，以 ms 爲單位）以後，資源進入準降級狀態。接下來若是持續進入 5 個請求，它們的 RT 都持續超過這個閾值，那麼在接下的時間窗口（DegradeRule 中的 timeWindow，以 s 爲單位）以內，對這個方法的調用都會自動地返回（拋出 DegradeException）。

異常比例 (DEGRADE_GRADE_EXCEPTION_RATIO)：當資源的每秒異常總數佔經過量的比值超過閾值（DegradeRule 中的 count）以後，資源進入降級狀態，即在接下的時間窗口（DegradeRule 中的 timeWindow，以 s 爲單位）以內，對這個方法的調用都會自動地返回。異常比率的閾值範圍是 [0.0, 1.0]，表明 0% - 100%。

異常數 (DEGRADE_GRADE_EXCEPTION_COUNT)：當資源近 1 分鐘的異常數目超過閾值以後會進行熔斷。

注意：爲了統計異常比例或異常數，須要經過 Tracer.trace(ex) 記錄業務異常。
