- Unify the extended interface as a few event handlers: onPass, onBlocked, onComplete and onError
- Polish related code

- Rename: whenComplete -> whenTerminate
- Execute the exit handler directly after the onExit hook of all slots

* 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.
* 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).

* Improve log info in SpiLoader, improve comment and test case
* Use error level in catch block, init ArrayList with capacity and improve add item to list
* Make slots loaded by SPI, mark all slots with @SpiOrder from -10000 to -1000, improve comment
* Reserve gateway and param slot chain builder (just extends DefaultSlotChainBuilder) and mark them as @Deprecated
* Move the legacy JUL methods from LogBase to BaseJulLogger.
* Add a JavaLoggingAdapter as the general JUL adapter for the Logger SPI, which makes it convenient to use (as the default logger).
* Add LoggerSpiProvider to resolve Logger SPI.
* Polish the logback demo.

* There are two types of logger for command center and common modules specified by annotation of `LogTarget`
* Add implementing examples in `sentinel-demo/sentinel-demo-log-logback`
* All implementations should support placeholder '{}'
