> We have two kinds of RegionCoprocessor: CoreCoprocessor or not.
> 1.The CoreCoprocessor(AccessController, TokenProvider, 
> SecureBulkLoadEndpoint...),  They have RegionEnvironmentForCoreCoprocessors 
> which expose RegionServerServices. And they involve authorization, 
> permission, etc, We don't need to support these CoreCoprocessor on 
> compactionServer
>  2. Not CoreCoprocessor: They have RegionEnvironment which do not expose 
> RegionServerServices, only offer Connection/ OnlineRegions, We can propose 
> RegionEnvironmentOnCS, offer Connection, but the OnlineRegions may leave to 
> discuss
