I mainly review points about the boundary to support specific logger.

Maybe we can just call it sentinel-logging-slf4j for short.

And is it necessary to create a new module in the same level as sentinel-extension called sentinel-logging? Thus some common logic can be put into a package like sentinel-logging-common maybe. Just a proposal and @sczyh30 you can comment it here.

Things change a lot.
So for summary the only undetermined point is:

Whether we should create a new module for integrations of logging.

Coming to README.md my opinion is making it simple which is enough. But i am okay if you have different viewpoint.

I mainly review points about the boundary to support specific logger.

And slf4j is mainly considered as a bridge which can integrate various loggers like logback, log4j, log4j2, commons-logging no matter what by configuration files, annotations or manually initializing.

jasonjoo2010

So i will approve this PR and maybe we can polish the structure of modules in another.
