   agree with @SteNicholas metadata should be a infrastructure service for ShardingSphere, we should provide a uniform interface for initialization, read, refreshing instead of distinguish with whether sharding or not. it seems that it will be a big refactor for sharding-jdbc & sharding-proxy.
   assume that task list is as below
   - [ ] investigate the usage of current metadata, clarify the function list of metadata (SQLParse, Route,Rewrite etc)
   - [ ] design a MetaData Model & MetaData Sevice, at first only consider about storing in memory
   - [ ] then consider about migrating to zookeeper or other registration
   
   @terrymanu is it ok for that
