> Currently RS Group pre/post hooks are called from RSGroupAdminServer.
> e.g. RSGroupAdminServer#removeRSGroup :
> {code}
>       if (master.getMasterCoprocessorHost() != null) {
>         master.getMasterCoprocessorHost().preRemoveRSGroup(name);
>       }
> {code}
> RSGroupAdminServer#removeRSGroup is called by RSGroupAdminEndpoint :
> {code}
>         checkPermission("removeRSGroup");
>         groupAdminServer.removeRSGroup(request.getRSGroupName());
> {code}
> If permission check fails, the pre hook wouldn't be called.
