[#32] Add request sender classifier
ACL has to classify request senders by roles: - owner of the container, - request from container or inner ring node, - any other request. According to this roles ACL checker use different bits of basic ACL to grant or deny access. Signed-off-by: Alex Vanin <alexey@nspcc.ru>
