Description for reviewers

The new Nebius scheme for checking permissions for cluster root container worked only for http requests (because TEvRequestAuthAndCheck works only in case of http requests). This PR fixes grpc methods (like getting/setting cluster config), if we use AdministrationAllowedSIDs together with folder_id cluster attribute.
