Fix the bug of circuit breaker half-open state transformation when request is blocked by upcoming rules (#1645) 
* Refactor the workflow to fix the bug that circuit breaker may remain half-open state forever when the request is blocked by upcoming rules: revert the state change in exit handler (as a temporary workaround)
* Add exit handler in Entry as a per-invocation hook.

Eric Zhao c0c27c86b7 Refactor degrade hierarchy with new circuit breaker mechanism and improve strategy 
* Add `CircuitBreaker` abstraction (with half-open state) and add circuit breaker state change event observer support.
* Improve circuit breaking strategy (avg RT → slow request ratio) and make statistics of each rule dependent (to support arbitrary statistic interval).
* Add simple "trial" mechanism (aka. half-open).
* Refactor mechanism of metric recording and state change handling for circuit breakers: record RT and error when requests have completed (i.e. `onExit`, based on #1420).
