Support customized origin parser in Apache Dubbo 2.7.x adapter and unify config (#1617)

* Support customized origin parser in Apache Dubbo 2.7.x adapter
* Unify Dubbo callback registry (for fallback and origin parser) into DubboAdapterGlobalConfig
* Polish default fallback implementation (wrap exception with RpcResult rather than directly throw it out)

## Global fallback

Sentinel Dubbo Adapter supports global fallback configuration.
The global fallback will handle exceptions and give replacement result when blocked by
flow control, degrade or system load protection. You can implement your own `DubboFallback` interface
and then register to `DubboFallbackRegistry`. If no fallback is configured, Sentinel will wrap the `BlockException`
then directly throw it out.
and then register to `DubboAdapterGlobalConfig`.
If no fallback is configured, Sentinel will wrap the `BlockException` as the fallback result.

Besides, we can also leverage [Dubbo mock mechanism](http://dubbo.apache.org/en-us/docs/user/demos/local-mock.html) to provide fallback implementation of degraded Dubbo services.
